Difluoroamines, synthesis

Difluoroamine is one of the most suitable agents for the synthesis of organic difluoroamino and geminal bis(difluoroamino) derivatives of different classes of compounds (106, 109,121). 

Synthesis of the parent compound 150, cyclodiazomethane, from SchifT bases of formaldehyde and difluoroamine, also proceeds with dealkylation. ... 

Graham (1962) described a direct one-step synthesis of diazirine by the reaction of difluoroamine (HNF2) with er butyl- or octyl azomethine (H2C=N —R) in CCI4 solution in a vacuum system. A yield of 62<7o was reported without any further information on mechanistic details. It seems that dealkylation and defluorination take place in the transient l-alkyl-2-fluoro-diaziridine (5.62, 5-15).
