The Reactions of Hexachlorocyclotriphosphazatriene with Ligands Including Mercapto Groups

Abstract

In this work, the reactions of hexachlorocyclotriphosphazatriene (trimer), N ₃ P ₃ Cl ₆ 1, with 2-mercapto-1-methylimidazole (methimazole) 2, 2-mercaptopyrimidine 3, and 2-mercaptopyridine 4 were discussed. Mono- (5) and pentasubstituted (6) phosphazenes were obtained from the reaction of 1 with 2-mercapto-1-methylimidazole. Both mono- (7) and disubstituted geminal (8) phosphazenes were obtained from the reaction of 1 with 2-mercaptopyrimidine. But phoshazene or any phosphorus compound could not be isolated from the reaction of 1 with 2-mercaptopyridine.
