es 4a-h and 5e. The influence of the pentacoordinated phosphorus atom on the stereoselectivity of the Pudovik reaction might be attributed to the involvement of the rigid spirophosphoranide (PV) intermediate in the addition reaction. Selective and one-pot hydrolysis of these P-C bond spirophosphoranes readily proceeds either at room temperature in the presence of moist solvents to give the corresponding

Reaction of the hydridophosphoranes (1a and 2) with chlorophosphines RR'PCl or with a pentacoordinated chlorophosphorane 7 in the presence of triethylamine gave new phosphorus-phosphorusbondedcompounds in good yields. They have been characterized by means of nmr and elemental analysis.

The triethylammomium salt of the phosphoranethiolate (3) has been isolated from the reaction of elemental sulphur with the conjugate base of the parent hydridophosphorane; its structure has been established by elemental analysis and n.m.r. (31P, 1H, 13C) and i.r. spectroscopy.
