Ukrainica Bioorganica Acta| Summary: | Reactions of (poly)fluoroalkylated NH-iminophosphonates with nitromethane, trimethylsilylcyanide, and diphenylphosphine oxide lead to respective fluorinated β-nitro-α-aminophosphonates, α-cyano-α-aminophosphonates, and heminal bisphosphonates. Reaction with 3-aminocrotonitrile 5 proceds at the β-position of enamine. In the case of α-imino chlorodifluoroethylphosphonate 1c the reaction is accompanied by an unusual nucleophilic substitution of the chlorine atom in CF2Cl group with the formation of pyrroline bearing a difluoromethylated aminophosphonate moiety |
