ETUDE DE LA REACTIVITE DU TRIS(TERTIOBUTYL)PHENYLDITHIOPHOSPHORANE

Heating of tris(tertiobutyl)phenyldithiophosphorane gives rise to an isomer with a tetracoordinated phosphorus atom.The action of triphenylphosphine loads to a tricyclophosphathiane which can be transformed in diphosphene by an excess of triphenylphosphine.Reactions with various nucleophilic derivatives (pyridine, triethylamine, diethylamine, butylamine, water, tetraphenylarsonium chloride) are described.

ISOLATION AND CHARACTERIZATION OF A STABLE DITHIOXOPHOSPHORANE

A sterically protected dithioxophosphorane, 2,4,6-tri-t-butylphenyldithioxophosphorane, has been isolated and characterized for the first time as a stable compound.

Reaction of the Diphosphene ArP=PAr (Ar = 2,4,6-But3C6H2) with Sulphur: Isolation and X-Ray Structure of the Diphosphene Monosulphide

The diphosphene ArP=PAr (Ar = 2,4,6-But3C6H2) reacts with elemental sulphur to give the stable monosulphide ArP(S)=PAr (2) whose structure was confirmed by an X-ray analysis; when treated with hexamethylphosphorous triamide, (2) reverts to the starting diphosphene but thermal and photochemical isomerisation of (2) gives the thiadiphosphirane Ar-cyclo-Ar.
