9,10-二甲基-9,10-二硅蒽二聚体(2)由9,10-二氢-9,10-二硅蒽(1a)与2当量锂反应制得。2与过量的锂或钾反应,通过二价阴离子3生成9,10-二硫代或9,10-二钾基-9,10-二甲基-9,10-二硅蒽(4a,B),其中一个Si-Si键已断裂。4a经a,w-二氯聚硅烷处理后,分别转化为相应的环状化合物6-9。
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.
