copper(I)-catalyzed cyanation of aromatichalides at room temperature has been developed. The sp2 cyanation reaction exhibits outstanding tolerance to functionalgroups including primary amines and carboxylic acids, and chemoselectivity to SN2-reactive alkyl chlorides. Mechanistic investigations indicate that the reaction occurs via a single-electron transfer (SET) between the aryl halide and an excited copper(I)

A new one-pot synthesis of C2-hydroxypropyl-substituted imidazolinium salts via the ringopening of tetrahydrofuran (THF) with N,N′-disubstituted diamines has been developed. Preliminary studies of the reaction mechanism suggest the CO2-promoted oxidative ringopening of THF followed by Hg(II)-mediated oxidation of an imidazolidine intermediate. These novel C2-substituted imidazolinium salts have shown
