Reaction Steps

Hydrazine (0.67 g, 0.02 mole) in methanol (5 ml) was stirred in a dry ice-acetone bath while pentafluorothioacetyl chloride (1.8 g, 0.0088 mole) in ether (3 ml) was added dropwise. After 15 minutes at 0° C., the mixture was poured into water and the insoluble material (0.35 g, mp 271° C. dec) was removed. An additional 0.7 g, mp 270° C. dec was recovered by concentrating the ether solution. Total yield of N,N'-bis(pentafluorothioacetyl)hydrazine is 1.05 g (66%); 1H NMR (acetone-d6): 4.78 (pentuplet); IR (KBr): 3190 (NH), 1635 (C=O), 895°-825 (SF5).
