An efficient multicomponent dipolar cycloaddition for the synthesis of polycyclic fused pyrrolizidines was developed using N-aromatic zwitterions, aldehydes, and amino acids. The developed reactions proceed through azomethine ylides generated in situ from the decarboxylated reactions of aldehydes and amino acids followed by the [3 + 2] cycloaddition of N-aromatic zwitterions under mild reaction conditions.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Recommanded Product: H-HoPro-OH

The reaction of c/s-[FeIII(cyclam)CI2]CI with 1 equiv of sodium N-diethyldithiocarbamate, toluene-3,4-dithiolate, and maleonitriledithiolate in methanol in the presence of triethylamine afforded the cations [FeIII(cyclam)(Et2dtc)]2+ (1), [FeIII(cyclam)(tdt)]+ (2), and [FeIII(cydam) (mnt)]+ (3), which were isolated as triflate, hexafluorophosphate, and tetrafluoroborate salt, respectively, using sodium triflate, potassium hexafluorophosphate, or sodium tetrafluoroborate as the source for the counteranion. Complexes 1, 2, and 3 possess an S = 1/2 ground state (low-spin ferric d5). These salts were characterized by X-ray crystallography, UV-vis, Moessbauer, and electron paramagnetic resonance spectroscopies. Cyclic voltammetry revealed that 2 and 3 are reversibly one-electron-reduced, generating neutral 2red and 3red, respectively, and one-electron-oxidized, generating dicationic 2ox and 3ox, respectively. Fe and S K-edge X-ray absorption spectroscopy (XAS) revealed that 2 (S = 1/2) and 2ox (S = 0) possess a low-spin ferric ion. Complexes 2 and 3 are S,S-coordinated to a closed-shell dithiolate(2-) ligand, whereas 2ox and 3ox consist of a lowspin ferric ion antiferromagnetically coupled to a dithiolate(1-) pi radical ligand. They are singlet diradicals [FeIII(cyclam)(dithiolate·)] 2+. The analysis of the sulfur K pre-edge transitions reveals significant multiplet effects in the spectra of 2 and 2ox, which provide rare experimental evidence for a singlet diradical description for 2ox. Moessbauer spectroscopy on frozen solutions of 2 red clearly show the presence of a high-spin ferrous ion (S = 2). The experimentally established electronic structures of the three members of the electron transfer series [Fe(cyclam) (dithiolate)]2+,+,0 have been verified by broken symmetry density functional theoretical calculations, which have been calibrated against the experiment by calculating XAS and Moessbauer spectra.

A general method for alkali-metal-promoted reductive difunctionalization of alkenes has been developed by means of reduction-resistant alkoxy-substituted electrophiles. A series of 1,2-diboration and 1,2-dicarbofunctionalization products can be synthesized by employing trimethoxyborane and strained cyclic ethers such as oxirane and oxetane. In addition, unsymmetrical carbo- or thioborations have been accomplished via sequential treatment with trimethoxyborane and carbon or sulfur electrophiles.

Electric Literature of 51207-66-0, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.51207-66-0, Name is (S)-(+)-1-(2-Pyrrolidinylmethyl)pyrrolidine, molecular formula is C9H18N2. In a Article，once mentioned of 51207-66-0

A highly crystalline new precursor of CHA-type zeolite AlPO4-34 was obtained by using an aluminophosphate gel with a chiral diamine [(S)-(+)-1-(2-pyrrolidinylmethyl)pyrrolidine; C9H18N2] as an organic structure directing agent under hydrothermal synthesis conditions. This precursor (called GAM-1) was changed into the zeolite AlPO4-34 which had a high porosity (the Brunauer-Emmett-Teller (BET) surface area is approximately 700 m3 g-1) using calcination. The GAM-1 obtained was characterized by various measurements, e.g., powder X-ray diffraction, scanning electron microscopy, and solid-state nuclear magnetic resonance spectroscopy, and so on. Structure determination from powder diffraction data revealed that the new precursor GAM-1 has triclinic symmetry [space group P1, a = 9.16535(11) A, b = 9.23042(11) A, c = 9.29228(11) A, alpha = 79.8243(7), beta = 87.4593(7), gamma = 86.5365(7)] and the chemical formula was estimated to be: Al6P6O24H2F2(C9H18N2)·2.5(H2O). It also revealed that a two edge sharing AlO4F2 octahedron with an Al-F-Al bridge was included in the framework. GAM-1 was transformed into AlPO4-34 with rhombohedral symmetry (R3) by elevating temperature to over 400 C. At high temperatures, AlO4F2 octahedron connectivity was changed into an AlO4 tetrahedron. The crystal structure of the dehydrated AlPO4-34 changed back to a triclinic symmetry (P1) model again after rehydration in the atmosphere.

Synthetic Route of 3030-47-5, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.3030-47-5, Name is N1-(2-(Dimethylamino)ethyl)-N1,N2,N2-trimethylethane-1,2-diamine, molecular formula is C9H23N3. In a article，once mentioned of 3030-47-5

Borane triethylamine reacts with lithium triphenylsilanide or lithium tert-butyldiphenylsilanide with formation of lithium (triphenylsilyl)trihydridoborate or lithium (tert- butyldiphenylsilyl)trihydridoborate. Complexation of the lithium cation with various ligands allows the isolation of compounds 1, 2a, and 2b. Trimethoxyborane reacts with lithium trimethylsilanide to form lithium tetrakis(trimethylsilyl)borate 3 and lithium tris(trimethylsilyl)methylborate 4. Mixed single crystals of 3 and 4 show an unexpected coordination of the lithium cation due to the lack of any supporting donor molecule. All silylborates exhibit short Si-B bond lengths compared to tricoordinated silylboranes.

Reaction of N-fluoropyridinium triflate with a base in dichloromethane gave 2-chloropyridine as the major product along with 2-pyridyl triflate and 2-fluoropyridine, regardless of the nature of the base. This base-initiated reaction was also shown to take place similarly in other halogenated alkanes, ethers, a nitrile, aromatics, a ketone, vinyl ethers, alcohols and trimethylsilyl acetate as solvents to give pyridine derivatives substituted with a solvent molecule (s) at the 2-position. N-(Trifluoromethanesulfonyloxy)-and (benzenesulfonyloxy) pyridinium salts were found to undergo the same base-initiated reaction. These reactions may be explained by a postulated singlet carbene (canonical formula 11b) produced through proton abstraction of N-substituted pyridinium salts. A similar carbene reaction may thus likely occur in the thermal decomposition of thiatriazole 10. Ab initio MO calculations revealed the structure and properties of the labile deprotonated N-fluoropyridinium cation and supported the carbene intermediate reaction mechanism rather than a pyridynium or pyridyl cation mechanism. Quarroz’s reports on the reactions of picolinic acid N-oxide and the reported reactions of pyridines with F2, CH3COOF or CsSO4F in solvents may be explained by this carbene mechanism.
