摘要

Unsymmetrical sulfides were prepared by the reactions of diphenylphosphinodithioate esters with organolithiums in tetrahydrofuran (THF) at− 78° C or at room temperature in fairly good or excellent yields. Similarly, methylene bis (diphenylphosphinodithioate) gave bis (alkylthio) methanes by reactions with organolithiums in good yields. The use of bad- smelling thiols is avoided and the phosphorus part can be recycled after sulfurization and ...
