Abstract
3-Bromo-2,2',4,4',6,6'-hexamethyl-3'-nitro-, 2,2'4,5',6-pentamethyl-3-nitro-, 3-bromo-2,2',4,6-tetramethyl-5'-nitro-, and 2,2',4,4',6,6'-hexamethyl-3-methoxycarbonylmethyl-3'-nitro-benzophenone were prepared by Friedel-Crafts acylation. The last compound was hydrolysed to 3-carboxymethyl-2,2',4,4',6,6'-hexamethyl-3'-nitrobenzophenone, which was resolved by way of the brucine salt; this demonstrates for the first time the existence of optical isomerism in suitably substituted benzophenones because of steric interactions between the o- and o'-substituents.
