PhICl2-Mediated Conversion of Enamines into α,N-Dichloroimines and Their Reverse Conversion Mediated by Zinc in Methanol
摘要:
Treatment of enamine compounds with iodobenzene dichloride (PhICl2) conveniently gives a variety of alpha,N-dichloroimines in high yields. This approach allows the double insertion of the chloro moiety, which is postulated to take place via the iodobenzene dichloride mediated oxidative alpha-chlorination of the enamine substrates followed by further N-chlorination of the imine intermediates. Furthermore, the obtained alpha,N-dichloroimines could be converted reversely into the original enamines under reductive conditions using zinc in methanol.
