Reaction of chloromethyliso(thio)cyanato(thio)phosphonates(-phosphinates) with phenol, ethanol, and thiols

Abstract

Chloromethyl)isocyanatophosphonates(-phosphinates) take up phenol to form carbamates whose b-cleavage gives rise to phenyl (chloromethyl)phosphonates(-phosphinates). (Chloromethyl)(thio)phosphinic-(phosphonic) isothiocyanates react with phenol at 20oC in the absence of catalyst to afford phenyl phosphinates(-phosphonates). (Alkylsulfanyl)carbamates formed by addition of thiols to (chloromethyl)iso(thio)cyanastophosphonates(-phosphinates) under the action of an equimolar amount of triethylamine undergo cyclization into 1,3,4-oxaza(thiaza)phospholines.
