Abstract

L'INVENTION A POUR OBJET UN PROCEDE DE DESULFURATION DE SULFURES ORGANIQUES ACCOMPAGNEE DE CYCLISATION, CARACTERISE EN CE QUE L'ON FAIT REAGIR UN B-LACTAME PORTANT UN GROUPE NUCLEOPHILE LIE A L'ATOME D'AZOTE PAR UN RADICAL ORGANIQUE DIVALENT NON SUBSTITUE OU SUBSTITUE ET UN GROUPE DITHIO OU POLYTHIO LIE A L'ATOME DE CARBONE ADJACENT, AVEC UN COMPOSE PHOSPHORO-ORGANIQUE TRIVALENT.THE OBJECT OF THE INVENTION IS A PROCESS FOR DESULFURATION OF ORGANIC SULPHIDES ACCOMPANIED BY CYCLING, CHARACTERIZED IN THAT A B-LACTAM BEARING A NUCLEOPHILIC GROUP BOUND TO THE NITROGEN ATOM BY A DIVALENT ORGANIC RADICAL UNSUBTITUTED OR REACTED. SUBSTITUTE AND A DITHIO OR POLYTHIO GROUP BOUND TO THE ADJACENT CARBON ATOM, WITH A TRIVALENT PHOSPHORO-ORGANIC COMPOUND.
