4-(ortho-hydroxyphenyl)-1,2,3-selenadiazole as a source of 2- benzofuranselenolate

Article abstract of DOI:10.1016/S0040-4039(99)00565-1

The novel 4-(ortho-hydroxyphenyl)-1,2,3-selenadiazole smoothly transforms into 2-benzofuranselenolate through potassium carbonate catalyzed selenadiazole ring cleavage. The presence of alkyneselenolate is proved by the formation of methyl(ortho-methoxy-phenylethynyl)selenide in the presence of methyl iodide. Alkylation and oxidation reactions of 2- benzofuranselenolate are described.
