Pentacoordinated tin is known since the late 1950s but little is known about the ability of lead to form similar structures. Originally we investigated the reaction between a number of tetraorganylphosphonium chlorides [PR 4 ] + Cl − (R=Me, Bu n ,

In a series of papers we showed that α-heterosubstituted phosphonate carbanions in a modified Horner-Emmons reaction are useful for the preparation of a variety of classes of compounds such as enamines, desoxybenzoines, trisubstituted vinyl chloride
