Description and Uses

Tetraphenylmethane is used to prepare a tetrapyridone tecton, which forms a diamondoid network with large internal chambers. It is also used in the preparation of 1-{4-[tris-(4-acetyl-phenyl)-methyl]-phenyl}-ethanone by Friedel-Crafts acylation reaction with acetyl chloride using aluminum chloride as catalyst.
