Abstract

Condensation o f 1-alkyl-2-aminopyridinium halides 1 with PCl3 in the presence of NEt3 yields, depending on the 1-substituent, pyridinylidene am inodichlorophosphines 2 or 4H-1,4,2-diazaphospholo[4,5-a]pyridines 3. The products are characterized by 31P, 1H and 13C NMR. Dimethylsulfate methylates the diazaphospholopyridines 3 at N-1.
