Amino-functionalized sulfonimidamides have been prepared by aziridinium ring-opening reactions and nucleophilic substitutions of sulfonimidoyl chlorides. Whereas the former reactions afford separable diastereomeric products, the latter provide single stereoisomers. Application of the resulting stereochemically homogeneous sulfonimidamides as ligands in asymmetric copper-catalyzed Henry reactions of aromatic aldehydes with nitromethane led to products with enantioselectivities up to 95% ee in good yields.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.20439-47-8. In my other articles, you can also check out more blogs about 20439-47-8

ZSM-5 zeolite is an efficient catalyst for both biomass deoxygenation and polyolefins cracking in pyrolysis process. In this study, wood-plastic composite (WPC), composed mainly of woody materials and thermoplastic polymers, was pyrolyzed using Py-GC/MS over phosphorus-modified HZSM-5 (P-HZSM-5) with varying P loadings (from 0 to 10 wt.%). The catalysts were prepared by wet impregnation method and characterized by XRF, XRD and NH3-TPD. The effects of pyrolysis temperature, time, heating rate, catalyst to WPC ratio and P loadings on the hydrocarbon distribution of WPC pyrolysis were studied. Pyrolysis conditions have significant effects on hydrocarbon distribution. Parent HZSM-5 facilitated aromatics formation, while P-HZSM-5 favored the formation of light aliphatic hydrocarbons (C4-C12). The yields of C4-C12 increased first with rising pyrolysis temperature from 450 to 550 C, then decreased over 550 C. Similarly, C4-C12 yields increased during the pyrolysis time from 15 to 30 s and decreased with the further prolonged time. A low heating rate (0.002 C/ms) favored the formation of light aliphatic hydrocarbons, while high heating rates (>0.2 C/ms) favored the formation of aromatics. Increasing catalyst to WPC ratio augmented aromatic selectivity. Hydrocarbon distribution strongly depended on the catalyst’s acidity, adjusted by varying P loading in P-HZSM-5. The highest yield of C4-C12 was obtained while using P-HZSM-5 with P loading of 3.5 wt.%.

The synthesis of a range of 1,2-diphospholides can be achieved by a one-pot procedure involving the reactions of aromatic primary phosphines bearing ortho-CH2 substituents with the superbase mixture of nBuLi/Sb(NMe2)3 in the presence of the Lewis base donor TMEDA (Me2NCH2CH2NMe2). The synthesis of the parent benzo-1,2-diphospholide and the substituted derivatives 4-methoxybenzo-1,2-diphospholide, 9-methylbenzo-1,2-diphospholide, and naphtho-1,2-diphospholide are reported from readily prepared primary phosphines. Bulk synthesis of the potassium salt of the previously reported 4,6-dimethylbenzo-1,2-diphospholide anion using this route provides a convenient starting material for reactivity studies.

The photochemical reaction between some alkenyl boronates and benzophenone is described. While a pinacol alkenyl boronate derivative gave the corresponding oxetane, the MIDA esters gave a tertiary alcohol derived from allylic hydrogen abstraction by triplet benzophenone and coupling of the radicals thus obtained. A theoretical work at DFT level of theory performed on a MIDA ester explained this behaviour showing that the formation of the tertiary alcohol is the most probable reaction. Furthermore, the theoretical calculations showed that the Paterno-Buechi reaction occurs giving the C,C biradical intermediate and this result is not in agreement with the previous described hypothesis where electron poor alkenes gave mainly the C,O biradical intermediate.

An asymmetric intramolecular carbolithiation reaction was developed by combining the (-)-sparteine-mediated enantiotopos-differentiating deprotonation and the anionic 5-exo-trig cyclization. Achiral 6-phenylhex-5- enyl carbamates were efficiently cyclized furnishing regio-, diastereo- (dr >99:1), and enantioselectively (er >98:2) 1,2-trans-substituted cyclopentanes. The intermediate primary benzylic lithium-carbanion pairs were – in spite of their configurative lability – diastercoselectively substituted by versatile electrophiles creating a third consecutive stereogenic center. Additionally, some 4-functionalized 6-phenylhex-5-enyl carbamates were also cyclized in high yield to provide enantiomerically pure cyclopentanes incorporating three adjacent stereogenic centers.

A well-defined (BA)(AC)2 miktoarm star diblock copolymer, (PPEGMA32-b-PMMA41)-b-(PMMA45-b-PNIPAm19)2, is synthesized by the combination of ATRP and click reaction. The miktoarm star block copolymer and its precursors are characterized by means of NMR and SEC/MALLS measurements. The copolymer exhibits a low critical aggregation concentration in aqueous solution. Micelles that self-assemble from the copolymer are prepared in aqueous solution below 15 C by a sonication method. The micelles have a PMMA core and a PPEGMA/PNIPAm corona and exhibit temperature sensitivity. Using celecoxib as a guest molecule, it is found that the loading capacity of the star copolymer is 8.8 wt% and the celecoxib release from the loaded self-assembly is temperature tunable.
