Abstract

4‐Selenophosphoryl‐1,2‐disubstituted imidazoles have been obtained by thermal decomposition of methyl 5‐(diamidoselenophosphoryl)imidazolium chlorides. The position of selenophosphoryl group in the imidazole ring was proved by ^1^H, ^13^C NMR spectroscopy, and X‐ray analysis. Previously unknown diamido‐ and dichloro(imidazol‐4‐yl)‐ phosphonites were synthesized, and differences in their reactivity compared to analogous 5‐phosphorylated imidazoles are shown. © 2010 Wiley Periodicals, Inc.

## Abstract 1,2‐Disubstituted imidazoles react with phosphorus(III) halides in pyridine regioselectively at position 5. The reaction proceeds the more readily, the higher the electron‐donating ability of the 2‐substituent in the starting imidazole. Hitherto unknown dihalo(imidazol‐5‐yl)phosphines h
