Abstract

Abstract 2, 5-Dichloro-1, 1, 1, 6, 6, 6-hexafluoro-3, 4-diazahexa-2, 4-diene (1) has been prepared in goodyield (60%) by the reaction of 1, 2-bis (trifluoroacetyl) hydrazine with a mixture of N, N-dimethylaniline hydrochloride and phosphoryl chloride. Nucleophilic displacement ofchlorine from azine 1 occurs readily on reaction with primary amines RNH 2 (R Pr i, Bu s, Ph, 4-FC 6 H 4, 2, 6-Cl 2 C 5 H 2 NCH 2-4) and with secondary amines ( ...
