Synthesis of novel perhalo-1,3-heterodienes from N-bromoperhalo-1-alkanimines
摘要:
The hydrolysis of several perhalo-1-bromo-3-aza-3-alkenes R(x)CF = NCF2CF2Br, R(x) = CF3, C2F5, ClCF2) affords the corresponding acid amide (R(x)CONHCF2CF2Br) in excellent yield. Dehydrofluorination of the amides using active KF gives the novel 1,3-heterodienes, perhalo-1-bromo-3-aza-4-oxo-2-alkenes (R(x)CON = CFCF2Br), in high yield. Details on the synthesis and properties of the new compounds are given along with some reaction chemistry of the dienes.
