Thermodynamic and kinetic acidity properties of nitroalkanes. Correlation of the effects of structure on the ionization constants and the rate constants of neutralization of substituted 1-phenyl-1-nitroethanes
Enantioseparation of nitriles (up to 92 % ee) and sulfoxides (up to 98 % ee) by inclusion crystallization with chiral organic salts of 4‐hydroxybenzoic acids and a chiral primary amine derived from l‐phenylalanine is described. This is the first example of the direct enantioseparation of aromatic nitriles without other functional groups.
traditional C −C cross‐coupling reactions they have been rarely used and Pd catalysts usually give a superior performance. Herein we report that in situ formed gold metal nanoparticles are highly active catalysts for the crosscoupling of allylstannanes and activated alkylbromides to form C −C bonds. Turnover numbers up to 29 000 could be achieved in the presence of active carbon as solidsupport, which allowed

Abstract Systematic studies of the coupling of benzylic with aryl halides are presented. The optimized reaction conditions for electron-deficient aryl halides cannot be applied to the electron-rich or neutral counterparts, and vice versa. The excellent functional group tolerance and broad substrate scope may enable the current work to be useful for the construction of diaryl methane products. Systematic
