摘要：

The deprotonation reactions of dimethyl (4-nitrophenyl)malonate and 4-bromophenyl-4-nitrophenylcyanomethane by tris[2-(2-methoxyethoxy)ethyl]amine, tributylamine and cryptand 222 were studied in polar aprotic solvents such as DMSO and acetonitrile by the kinetic, FT-IR and H-1 NMR spectroscopic methods. The mechanisms of the proton transfer reactions are discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
