摘要

As applications of the versatile Wittig reaction3f4 are directed toward the synthesis of more complex olefins, the requisite phosphonium salts must frequently incorporate labile functional groups and stereochemically sensitive center^.^^^^ The presence of sensitive functionality may limit the use of standard elevated temperature conditions (80-140" C) for salt formation3p4 and, therefore, provide impetus for developing a new mild method for ...
