9, 10-Dimethyl-9, 10-disilaanthracene dimer (2) was prepared by treatment of 9, 10-dihydro-9, 10-disilaanthracene (la) with 2 equiv of lithium. The reaction of 2 with excess lithium or potassium resulted in formation of 9, 10-dilithio-or 9, 10-dipotassio-9, 10-dimethyl-9, 10-disilaanthracene (4a, b), via the dianion 3, in which one Si—Si bond has been cleaved. On treatment with a, w-dichloropolysilanes, 4a was con-verted into the corresponding cyclic compounds 6—9, respectively.
