(4-ACETYLPHENYL)PHENYLMETHANE Chemical Properties,Usage,Production

Uses

1-(4-Benzylphenyl)ethanone is used in the preparation of di- and triarylmethanes through palladium-catalyzed reductive coupling of N-tosylhydrazones and aryl bromides.

Purification Methods

Distil it in a vacuum, then recrystallise it from EtOH (ca 1mL/g). The oxime has m 99.5o (from 60% aqueous EtOH). [Beilstein 7 H 449, 7 III 2176.]
