A direct synthesis of vinylphosphonium salts from a-trimethylsilyl ylides and non-enolizable aldehydes.

[摘要]：Reaction of a-silylated ylides with non-enolizable aldehydes proceeds by selective Peterson-type elimination, in contrast to prior literature reports. The described stereoselective synthesis provides a direct route to synthetically useful vinylphosphonium salts.
