## Abstract 1,2โDisubstituted imidazoles react with phosphorus(III) halides in pyridine regioselectively at position 5. The reaction proceeds the more readily, the higher the electronโdonating ability of the 2โsubstituent in the starting imidazole. Hitherto unknown dihalo(imidazolโ5โyl)phosphines h
## Abstract 4โSelenophosphorylโ1,2โdisubstituted imidazoles have been obtained by thermal decomposition of methyl 5โ(diamidoselenophosphoryl)imidazolium chlorides. The position of selenophosphoryl group in the imidazole ring was proved by ^1^H, ^13^C NMR spectroscopy, and Xโray analysis. Previously
