The interactions of phosphorylsulphenylhalides, phosphorylated disulphides, thio- and dithiophosphoric acids with diazo compounds were investigated. It has been shown that these reactions mainly lead to the insertion of methylene groups into S-Hal, S-S, S-H bonds. α-Chloromethyl-phosphorothio- and -dithioates are obtained from the corresponding phosphoryl- and thiophosphorylsulphenyl-chlorides. As for phosphorylsulphenylbromides, the reaction is accompanied by phosphoryl-thiophosphoryl rearrangements |
