Aliphatic N-substituted functional eight-membered cyclic carbonates were synthesized from N-substituted diethanolamines by intramolecular cyclization. On the basis of the N-substituent, three major subclasses of carbonate monomers were synthesized (N

A general method for copper-catalyzed arylation of sp (2) C-H bonds with p K a's below 35 has been developed. The method employs aryl halide as the coupling partner, lithium alkoxide or K 3PO 4 base, and DMF, DMPU, or mixed DMF/xylenes solvent. A var

A novel ruthenabicyclic complex with base shows excellent catalytic activity in the asymmetric hydrogenation of ketones. The turnover frequency of the hydrogenation of acetophenone reaches about 35 000 min–1 in the best case, affording 1-phenyletha
