Yu, Lei,Chen, Fenglin,Ding, Yuanhua
, p. 1033 - 1037 (2016/04/05)
Catalyst screening and optimization of reaction conditions allowed control of the organoselenium-catalyzed oxidative ring expansion of highly active methylenecyclopropanes to give substituted cyclobutanones selectively. This protocol employs H2O2 as a clean oxidant and generates no waste and, therefore, provides green access to useful, but not readily available, substituted cyclobutanones under mild conditions.

Reactions of (dimethylamino)phenylsulfoxonium mathylide with triphenylvinylphosphonium salts gave the corresponding cyclopropyltriphenylphosphonium salts (E-form) in high yields, when 1,8-diazabicycloundec-7-ene was used as a base.Reactions of cyclopropyltriphenylphosphonium salts with sodium hydride in the presence of trisamine afforded the corresponding ylides, which further reacted with aldehydes to give alkylidenepropanes in high yields.
