Abstract
Deprotonation of 'C-acids': benzoylmalononitrile (1), and 4-nitrophenylmalononitrile (2), triethoxycarbonylmethane (3), diethyl cyanomalonate (4) and ethyl 1,3-indandione-2-carboxylate (5), by 7-methyl-1,5,7-triaza-bicyclo[4.4.O]dec-5-ene (MTBD) and 1,8-bis(dimethylamino)naphthalene (DMAN) in acetonitrile was studied by FTIR and 1H NMR methods. The results demonstrate that the proton transfer mechanism from 'C-acids' to N-bases in acetonitrile is determined by different distributions of charge in the carbanion and the protonated N-base as well as by the structures of the C-acid and N-base molecules.
