A new, stereoselective interconversion of phosphinothio-phosphinoseleno compounds, reduction of phosphinoseleno derivatives and retro pishchimuka rearrangement based on methylthio- and methylselenophosphonium salts chemistry

The interconversion of thiono- into seleno compounds was found to proceed with retention of the configuration at phosphorus and the mechanistic course of this process has been proposed. The isomerization reaction of phosphinothiolates into thiono-isomers via the phosphonium salts has been developed and considered as the "retro Pishchimuka" rearrangement.

STEREOSPECIFIC INTERCONVERSION OF THIO- AND SELENOPHOSPHORYL COMPOUNDS

The conversion of chiral methyl-n-propylphenylphosphine sulphide into the corresponding selenide and the reverse reaction are easily accomplished by treatment of the corresponding methylthio- and methylselenophosphonium salts with sodium hydrogen selenide and sodium hydrogen sulphide, respectively.Both reactions occur with retention of configuration at phosphorus and high stereospecificity.
