Abstract (Chloromethyl) isocyanatophosphonates (-phosphinates) take up phenol to form carbamates whose β-cleavage gives rise to phenyl (chloromethyl) phosphonates (- phosphinates).(Chloromethyl)(thio) phosphinic-(phosphonic) isothiocyanates react with phenol at 20° C in the absence of catalyst to afford phenyl phosphinates (-phosphonates).( Alkylsulfanyl) carbamates formed by addition of thiols to (chloromethyl) iso (thio) ...
