Synthesis and crystal structure of 9,10-disilatriptycenes

Abstract
9,10-Disilatriptycenes 1a–1chave been synthesized by a novel route via o-trimethylsilylphenyllithium, a novel synthetic equivalent of o-halogenophenyl anion; the structure of the 9-methyl-10-hydroxy derivative 1c was determined by X-ray crystallography.
