General description

Biphenyl (BP) is a p-polyphenyl containing two phenyl rings with a non-planar conformation. Its synthesis from benzene by intermolecular direct C-H homocoupling in the presence of palladium-containing catalytic system has been described. Stereochemical studies of its structure have been reported. The nitration of BP using 95% nitric acid to form mononitrobiphenyl isomers has been investigated.

The first Suzuki cross-couplings of unactivated tertiary alkyl electrophiles are described. The method employs a readily accessible catalyst (NiBr(2)·diglyme/4,4'-di-tert-butyl-2,2'-bipyridine, both commercially available) and represents the initial example of the use of a group 10 catalyst to cross-couple unactivated tertiary electrophiles
