摘要：

Competitive of addition of CCl3- anions to N-alkyl-pyridinium salts and to vinyl acetate, t-butyl acrylate and benzaldehyde was studied in a two-phase system, chloroform I cone, aqueous NaOH, and in a homogeneous medium. The results support an interfacial mechanism for generation of carbanions and indicate that chloroform is deprotonated by NaOH at the interface. (C) 1999 Elsevier Science Ltd. All rights reserved.
