1. The Wittig Reaction - CCC/UPCMLD
Feb 12, 2007 · ratios that depend on the level of stabilization (charge delocalization) of the ylide. The Wittig reaction must involve a mechanism other than the betaine pathway. A synchronous ... An interplay of 1,2- and 1,3-steric interactions decides which diastereomeric oxaphosphetane will be favored. It is important to recall,
