Tetraphenylmethane Usage And Synthesis

Background

Molecules of tetrahedral symmetry, such as tetraphenylmethane (TPM) and its various analogues (sometimes quite distant) over the years, were amongst the most exploited models in crystal engineering. For example, phenyl embraces, which are cooperative supramolecular motifs composed by set of Csingle bondH ⋯ π attractive interactions have been recognized as fundamental interactions responsible for dense crystal packing of tetrahedrally-shaped species such as tetraphenylphosphonium, tetraphenylarsonium, and tetraphenylborate compounds. Another example of the significant role of TPM-like molecules is the introduction and development of molecular tectonics. Molecular tectonics is a strategy for the predictable construction of crystalline arrays from molecules called tectons. An inextricable feature of any tecton molecule is its shape and binding abilities enforce specific and directional arrangements of the same or complementary molecules[1].

Chemical Properties

white to pink powder or needles

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.
