Abstract Ketoximes react rapidly with X 2 PCl compounds were X= Ph, Me 2 N, EtO and X 2= OCH 2 CH 2 O at low temperatures (− 60 to− 80 C) in the presence of triethylamine to give a P III intermediate 2, which rearranges by a unimolecular process to the corresponding N- phosphinylated imine 3. Free radicals, formed by capture of the initially produced phosphonyl radical, are detected by ESR spectroscopy, and evidence for a radical cage ...
