Thermal rearrangement of thiocarbonyl-stabilised triphenylphosphonium ylides leading to (Z)-1-diphenylphosphino-2-phenylsulfenylalkenes
While thermolysis of thiocarbonyl-stabilised phosphonium ylides generally results in extrusion of Ph3PS to give alkynes, those with a PCH function instead undergo a novel P to S transfer of a phenyl group to give (Z)-configured 1-phosphino-2-su

Starting from acylalkylidenetriphenylphosphoranes 1 the corresponding thioacylalkylidenetriphenylphosphoranes 4 have been synthesized via the triflates 3 and converted into the salts 8. Some spectroscopic data of the new compounds are discussed.
