Synthesis and Crystal Structure of 9,10-Disilatriptycenes

Article abstract of DOI:10.1039/c39930001850

9,10-Disilatriptycenes 1a-1c have 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.
