Abstract
2,6-Dimethoxyphenylphosphetane sulfide has been synthesized by condensation of 2,6-dimethoxyphenylphosphine with 1,3-propanediol ditosylate and treatm ent of the resulting phosphetane with sulfur. Irradiation at 254 nm of the phosphetane sulfide was undertaken to determine the mode of photodissociati on and the types of reactive intermediates produced. Evidence is presented for the formation of both the corresponding arylphosphinidene sulfide ArP=S and the methylene(thioxo)phosphorane ArP(S)=CH2 as transient species. (C) 1999 Elsevier Science S.A.
