Article abstract of DOI:10.1016/0040-4039(91)80188-C

Reaction of 3-alkyl-2-aminocycloimmonium salts with PCl3 in presence of NEt3 gives a new class of functionalized dichlorophosphines which undergo dehydrohalogenation intramolecularly to form 1,3,4-diazaphospholo heterocycles.These dichlorophosphines show
