Synthesis and Properties of <i>g</i><i>em</i>-(Difluorocyclopropyl)amine Derivatives of Bicyclo[<i>n</i>.1.0]alkanes NowakIreneusz CannonJohn F. RobinsMorris J. 2004 Generation of difluorocarbene(carbenoid) in the presence of enamines derived from cyclic ketones results in overall insertion of CF<sub>2</sub> to produce bicyclic difluorocyclopropylamines. These adducts are very weakly basic, and their thermal stabilities vary markedly with their structures.
