p>π-Double bonds between phosphorus and carbon—a challenge

Abstract

A survey is given on the field of organophos- phorus compounds concerning PC-double bonds, which after isolated oberservations has developed vividly in the last decade and which in the meantime yielded the synthesis of hundreds of at room temperature stable acyclic compounds. Maintopics of this paper are proofs for the assumption of real p>π-bonds and the unexpected affinities between phosphaalkenes and alkenes, which can be proved by theoretically interesting pericyclic reactions and by their coordination chemistry. © 1987 IUPAC
