## Abstract 4โ€Selenophosphorylโ€1,2โ€disubstituted 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 Xโ€ray analysis. Previously
