The reaction of aqueous solutions of the preformed 1:1 Cu(ClO 4)2-polydentate amine with tetrasodium 1,2,4,5-benzene tetracarboxylate (Na4bta) afforded three different types of polynuclear compounds. These include the tetranuclear complexes: [Cu 4(Medpt)4(mu4-bta)(ClO4) 2(H2O)2](ClO4)2· 2H2O (1), [Cu4(pmdien)4(mu4-bta) (H2O)4](ClO4)4 (2), [Cu 4(Mepea)4(mu4-bta)(H2O) 2](ClO4)4 (3), [Cu4(TPA) 4(mu4-bta)](ClO4)4·10H 2O (4) and [Cu4(tepa)4(mu4-bta)] (ClO4)4·2H2O (5), the di-nuclear: [Cu2(DPA)2(mu2-bta)(H2O) 2]·4H2O (6), [Cu2(dppa) 2(mu2-bta)(H2O)2]·4H 2O (7) and [Cu2(pmea)2(mu2-bta)] ·14H2O (8) and the trinuclear complex [Cu3(dppa) 3(mu3-bta)(H2O)2.25](ClO 4)2·6.5H2O (9) where Medpt = 3,3?-diamino-N-methyldipropylamine, pmedien = N,N,N?,N?, N?-pentamethyldiethylenetriamine, Mepea = [2-(2-pyridyl)ethyl]-(2- pyridylmethyl)methylamine, TPA = tris(2-pyridylmethyl)amine, tepa = tris[2-(2-pyridyl)ethyl)]amine, DPA = di(2-pyridymethyl)amine, dppa = N-propanamide-bis(2-pyridylmethyl)amine and pmea = bis(2-pyridylmethyl)-[2-(2- pyridylethyl)]amine. The complexes were structurally characterized by elemental analyses, spectroscopic techniques, and by X-ray crystallography for complexes 1, 2, 4, 6, 7 and 9. X-ray structure of the complexes reveal that bta 4- is acting as a bridging ligand via its four deprotonated caboxylate groups in 1, 2 and 4, three carboxylate groups in 9 and via two trans-carboxylates in 6 and 7. The complexes exhibit extended supramolecular networks with different dimensionality: 1-D in 2 and 4 due to hydrogen bonds of the type O-H···O, 2-D in 1 and 7, and 3-D network in 6 as a result of hydrogen bonds of the types N-H···O and O-H···O. Magnetic susceptibility measurements showed very weak antiferromagnetic coupling between the CuII ions in 1-5, 7-9 (|J| = 0.02-0.87 cm-1) and weak ferromagnetic coupling for 6 (J = 0.08 cm-1).

Synthesis of functionalized polylactide by cationic activated monomer polymerization

Functionalized polylactides (PLAs) containing acryloyl, methacryloyl or propargyl end groups have been obtained by cationic ring-opening polymerization performed in the presence of appropriate alcohols (HEMA, HEA, propargyl alcohol) as initiators and triflic acid as a catalyst. 1H NMR, MALDI TOF and GPC analysis indicated almost quantitative initiation and confirmed the expected structure and molecular masses of the obtained PLAs. The conditions were found in which transesterification process (usually accompanying the cyclic esters propagation) can be avoided. PLAs functionalized with double bond were successfully homopolymerized and copolymerized with butyl acrylate in the presence of AIBN. PLA with triple bond at one chain end was effectively coupled with a model azide by 1,3-dipolar Huisgen cycloaddition (“click” reaction) in order to prove its ability to be further functionalized.

2,6-diisopropylphenylamides of potassium and calcium: A primary amido ligand in s-block metal chemistry with an unprecedented catalytic reactivity

Transamination of KN(SiMe3)2 with 2,6-diisopropylphenylamine (2,6-diisopropylaniline) in toluene at ambient temperature yields [K{N(H)Dipp}·KN(SiMe3)2] (1) regardless of the applied stoichiometry. Recrystallization of 1 in the presence of tetramethylethylenediamine (TMEDA) and tetrahydrofuran (THF) leads to the formation of [(mu-thf)K2{N(H)Dipp}2]? (2), whereas potassium bis(trimethylsilyl)amide remains in solution. Addition of pentamethyldiethylenetriamine (PMDETA) gives [(pmdeta)K{N(H)Dipp}]2 (3). In contrast to the thf and pmdeta adducts, which lead to dissociation of 1 into homoleptic species, addition of bidentate dimethoxyethane maintains the mixed complex [(dme)K{mu-N(SiMe3)2}{mu-N(H)Dipp}K] 2 (4). A complete transamination of 2,6-diisopropylaniline with KN(SiMe3)2 in toluene at 100 C yields [K{N(H)Dipp}] (5), which reacts with CaI2 to give [(thf)nCa{N(H)Dipp} 2] (6), [(pmdeta)Ca{N(H)Dipp}2] (7), and [(dme) 2Ca{N(H)Dipp}2] (8), depending on the solvents and coligands. Excess potassium 2,6-diisopropylphenylamide allows the formation of the calciate [K2Ca{N(H)Dipp}4]? (9). Hydroamination of diphenylbutadiyne with 2,6-diisopropylaniline in the presence of catalytic amounts of 9 gives tetracyclic 2,6-diisopropyl-9,11,14,15- tetraphenyl-8-azatetracyclo[8.5.0.01,7.02,13]pentadeca-3, 5,7,9,11,14-hexaene (10). Solid-state structures are reported for 2-4 and 7-10. Compound 10 slowly rearranges to tetracyclic 5a,9-diisopropyl-2,3,10,11- tetraphenyl-5a,6-dihydro-2a1,6-ethenocyclohepta[cd]isoindole (11), which is slightly favored according to quantum chemical studies.

Determination of Rate Constants for the Activation Step in Atom Transfer Radical Polymerization Using the Stopped-Flow Technique

The use of stopped-flow techniques to measure activation rate constants for model systems in copper-mediated atom transfer radical polymerization (ATRP) was studied. The structures of model alkyl halides and complexing ligands used in conjunction with CuBr or CuCl were shown. The time dependent absorption spectra recorded for the reaction of CuBr/2dNbpy in the presence of excess EBriB and TEMPO in CH3CN at 25C was shown. The activation rate constant and the catalyst structure were correlated and the deactivation rate constants for ATRP was determined using the persistent radical effect.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 3030-47-5, you can also check out more blogs about3030-47-5

Photocontrollable release and enhancement of photodynamic therapy based on host-guest supramolecular amphiphiles

A light-controlled porphyrinic photosensitizer release system was developed based on host-guest TPP-Azo/PEG-beta-CD supramolecular amphiphiles, which could significantly enhance the efficiency of photodynamic therapy. TPP-Azo was prepared via esterification between TPP and Azo derivatives, and further used to construct supramolecular amphiphiles with PEG-beta-CD. TEM images showed that TPP-Azo/PEG-beta-CD amphiphiles can self-assemble into spherical micelles, and then disaggregate under irradiation with 365 nm UV light. The phototoxicity and bio-distribution of TPP-Azo/PEG-beta-CD micelles against the MCF-7 cell line were also evaluated by MTT assay, flow cytometry and confocal scanning laser microscopy, respectively. According to MTT assay, the IC50 of the spherical micelle was 31.2 mug mL-1, but it became 20.6 mug mL-1 upon pre-irradiation with 365 nm UV light. This shows for the first time that UV light can well stimulate the release of porphyrin photosensitizers and improve the photodynamic therapy efficiency based on the system of host-guest supramolecular amphiphiles.

Fluorine-free and fluorine containing MOCVD precursors for electronic oxides: A comparison

MOCVD processes adopting two different precursors Sr(tmhd) 2pmdeta and Sr(hfac)2tetraglyme have been compared. In situ FT-IR monitoring shows that Sr(hfac)2tetraglyme posses suitable thermal stability upon sublimation and good mass-transport properties. By contrast, Sr(tmhd)2pmdeta posses lower stability which precludes efficient sublimation/evaporation processes, thus requiring reactors equipped with liquid delivery systems for efficient MOCVD processes. Insights on the MOCVD process have been obtained combining in situ FT-IR and ex situ XRD, XPS, SEM and EDX techniques. Homogeneous films have been deposited on Pt/TiN/SiO 2/Si substrates in the 300-500C temperature range. XRD and XPS analyses have shown that fluorine or carbonate containing films are obtained adopting Sr(hfac)2tetraglyme or Sr(dpm)2pmdeta, respectively.

The mechanism of lithiation and nitrile insertion reactions of beta-methylazines: Evidence from the structure of 3-C5H4NCH=C(Ph)N(H)C(Ph)=NLi · PMDETA

A 1:1:1 reaction of 3-methylpyridine, 1, with LDA and PhCN in the presence of PMDETA gives the title complex 6, shown by X-ray crystallography to be the first monomeric iminolithium. The isolation of 6, and of a cyclised product 8 when a 3:10:3 reaction of 1:LDA:PhCN is carried out, suggest a mechanism for previously published cyclisation reactions of beta-methylazines.
