Reaction of diphenylacetylene with organophosphides - A stereospecific synthesis of vinyl phosphines.

Reaction of lithium diphenyl phosphide with diphenylacetylene producing high yields of stereochemically pure vinyl phosphides in presence of primary or secondary amine

Lithium cleavage of unsaturated vicinal di-tert-phosphines

Abstract Lithium metal in tetrahydrofuran has been found to react with ethynylenebis(diphenylphosphine) and cis - or trans -1,2-vinylenebis(diphenylphosphine) to produce lithium diphenylphosphide in high yield. Possible mechanistic paths are discussed. In this connection the reactions of the vinylenebis- and ethynylenebis(diphenylphosphines) with lithium diphenylphosphide have been examined and the results are discussed.

A new class of radical cations: the radical cations of 1,4-diphosphoniacyclohexa-2,5-diene salts

Electrochemical reduction of a series of 1,4-diphosphoniacyclohexadiene salts has produced a new class of radical cations for which e.s.r. data are presented.
