Abstract

Stable 4, 7-disubstituted benzotrichalcogenoles containing sulfur and/or selenium atoms in the five-membered ring were systematically and selectively prepared in good yields by reaction of the corresponding benzodichalcogenastannoles, a synthetic equivalent of benzenedichalcogenols, with an S1 or Se1 source. Characterization of these new trichalcogenole frameworks was performed by multi-nuclear NMR studies and X-ray ...
