Nucleophilic Substitution Reactions of Heterocyclic Amines and Acyclic Diamineswith Chlorofluoroolefins and Hexafluoropropylene Oxide

摘要

The reactions of CH3N(H)CH2CH2N(H)CH3, CH3N(H)CH2CH2CH2N(H)CH3, and the cyclicamines piperazine, N-phenylpiperazine, and N-methylpiperazine with both cyclic and acyclic 1-2-dichloroperfluorolefins are reported. Nucleophilic attack occurs at olefinic carbon, followed, in some cases, by cyclization and B-elimination. A variety of unusual polyfluorinated tertiary amines and heterocycles are synthesized. (jg).
