SYNTHESIS AND CRYSTAL-STRUCTURE OF 9,10-DISILATRIPTYCENES

9,10-Disilatriptycenes 1a-1c have been synthesized by a novel route vi a o-trimethylsilylphenyllithium,a novel synthetic equivalent of o-halo genophenyl anion; the structure of the 9-methyl-10-hydroxy derivative 1c was determined by X-ray crystallography.
