2-Chloro-3-phenyl-3-trimethylsilyl-thiaphosphirane (5) opens the ring via the thiaphosphirene to give a thiocarbonylphosphinidene - and not a phosphaethynesulfide - as an intermediate 1,3-dipole.

2-CHLOR-1-THIA-2-PHOSPHIRANE -SYNTHESE UND REAKTIONEN - HINWEISE FUER DEN 1.3-DIPOL PhC(1+)=P-S(1-)
The title compounds are obtained by reaction of 5-methyl-1,3,4-oxathiazol-2-one with phosphaalkenes.Arguments for the intermediate formation of the P-analog of nitrilsulfides (via the thiaphosphirenes) as 1,3-dipoles are presented.
