摘要

Alkali metal hydroxides, in the presence of a quaternary ammonium salt as a catalyst- oatalytio two-phase, CTP, system-are the most convenient for the deprotonation of haloforma and generation of dihalocarbenes2. On the other hand, very little is known about the applicability of this system for the generation of dihalomzthyl carbanions from the corresponding dihalomethanes. To the best of our knowledge, the only informatIon deals ...
