摘要:

A remarkable feature of diethyl-1,3-butadiene-phosphonate, unlike the dienephosphonium salts,2,3is that it undergoes a simple Michael addition with enolates of aldehydes and ketones without the loss of the phosphorus group.4Whether such a difference in reactivity exists between the two-carbon reagents, vinyltriphenylphosphonium bromide15and diethyl vinylphosphonate26is the subject of this investigation.
