Abstract

A facile and effective synthetic procedure for 1,3-diselenole-2-selone-4,5-diselenolate (dsis, 2) has been established. The utilization of 2 for the synthesis of selenocycle-fused tetraselenafulvalene derivatives is also reported.

Key words

lithiation - diselenolate ligands - protecting groups - ring-closure reaction - selenium-containing heterocycles

    (c) Essentially there should be no difference between cyanoethyl- and methoxycarbonylethyl- groups as a protecting group for thiolate or selenolate. However, in case of TSF selenolate derivatives, incorporation of cyanoethyl groups often leads to a serious decrease of solubility, making the subsequent deprotection/realkylation protocol difficult. Thus, we prefer the methoxycarbonylethyl group as a protecting group for the TSF selenolates.
