New method for the preparation of octathiotetraphosphetanes on the basis of elemental phosphorus and sulfur: Structure and properties

摘要

New octathiotetraphosphetane ammonium salts are obtained based on the reaction of white phosphorus (?4) and elemental sulfur with aliphatic mercaptans in the presence of amines (morpholine, methylmorpholine, pyrrolidine, and N,N-dimethylbenzylamine). The salts of octathiotetraphosphetane are characterized by IR/Raman spectroscopy. Several common IR and Raman bands can be used as structural markers for establishing the structures of [P _4S_8]~4- anion in new compounds.
