✦ Synopsis

Competitive of addition of CCI-3 anions to N-alkyi-pyridinium salts and to vinyl acetate, t-butyl acrylate and benzaldehyde was studied in a two-phase system, chloroform / conc. aqueous NaOH, and in a homogeneous medium. The results support an interracial mechanism for generation of carbanions and indicate that chloroform is deprotonated by NaOH at the interface.
