Ylide: Other types, Phosphonium ylides & Reactions

An ylide (/ˈɪlaɪd/) or ylid (/ˈɪlɪd/) is a neutral dipolar molecule containing a formally negatively charged atom (usually a carbanion) directly attached to a heteroatom with a formal positive charge (usually nitrogen, phosphorus or sulfur), and in which both atoms have full octets of electrons. The result can be viewed as a structure in which two…
