The structure of the functionalized trans-diphosphiranes 1a-e, obtained by reaction of halogenocarbenes with the trans-diphosphene is confirmed by X-ray diffraction.The photolysis of 1a-e lead to the functionalized cis- and trans-1,3-diphosphapropenes 2a-e as major products, via the diphosphiranyl 7 and the diphosphapropenyl 8 radical intermediates.The latter are characterized by ESR spectroscopy using the spin-trap method.The trans configuration of 2a is also confirmed by X-ray diffraction.The mechanism of the ring-opening, involving P-P bond rupture, is discussed.

The cycloaddition reactions on Phosphorus Chemistry has allowed a new development of the three membered ring organophosphorus compounds.Starting from functionalized diphosphiranes obtained by action of carbenes on diphosphenes, we have studied their ring opening reactions leading to carbon insertion into P-P bond.

The functionalized diphosphiranes 1a-c, in presence of Lewis acid, undergo two kinds of reaction:the ring opening leading to the phosphenium-phosphonium ion 2a-c obtained according to an electrocyclic reaction and the fragmentation giving phosphaalkene 3a
