摘要

The rate and course of reaction of triphenylphosphine (Ph3P) with organic sulphur compounds (R· Sx· R′; R, R′= alkyl or alkenyl, x= 2 or 4) at 80° or 140° depend on the nature of R and R′ and on the reaction medium. Dialkyl-and diaralkyl tetrasulphides (R R′= iso-Pr; n-Bu; T-Bu; PhCH2) yield triphenylphosphine sulphide and dialkyl-or diaralkyl disulphides which are resistant to further attack by Ph3P, even at 140°. Dialkenyl-and ...
