Abstract

It has been demonstrated that 2, 2'-biphenylenedilithium (I) reacts with 5-chloro-5- methyldibenzosilole (111) to give 5, 5'-spirobi-[dibenzosilole](11) and 5, 5- dimethyldibenzosilole. Furthermore, I1 was the only compound isolated from the reaction of I with hexachlorodisilane. Compound I1 was readily cleaved by phenyllithium in diethyl ether or in tetrahydrofuran to yield 5-(2-biphenylyl)-5-phenyldibenzosilole, a compound which ...
