Abstract

[reaction: see text] Generation of difluorocarbene(carbenoid) in the presence of enamines derived from cyclic ketones results in overall insertion of CF2 to produce bicyclic difluorocyclopropylamines. These adducts are very weakly basic, and their thermal stabilities vary markedly with their structures.
