Abstract

Phosphonium ylide has been the most popular reagent for Wittig type olefination of ketones.1 The ylide, however, was also equipped with a strong basicity which often leads to an enoliza- tion of the starting carbonyl compound. At the same time, it of- ten suffers from a lack of nucleophilicity. For these drawbacks arose the necessity to develop the novel alkylidenation reagents. Among them, gem-dimetal compound showed the promising re- sults.2 As the ...
