Selective oxygenation of 4,4'-dimethylbiphenyl with molecular oxygen, catalyzed by 9-phenyl-10-methylacridinium ion via photoinduced electron transfer.

Kyou Suga et al.

The journal of physical chemistry. A, 109(44), 10168-10175 (2006-07-15)

Photooxygenation of 4,4'-dimethybiphenyl with oxygen occurs efficiently in the presence of 9-phenyl-10-methylacridinium perchlorate (AcrPh(+)ClO(4)(-)) under visible light irradiation in O(2)-saturated chloroform (CHCl(3)) to yield 4-(4'-methylphenyl)benzaldehyde as a main oxygenated product. Prolonged photoirradiation afforded the further oxygenated product, 4,4'-diformylbiphenyl. The reactive

Intramolecular isotope effects for benzylic hydroxylation of isomeric xylenes and 4,4'-dimethylbiphenyl by cytochrome P450: relationship between distance of methyl groups and masking of the intrinsic isotope effect.

K R Iyer et al.

Biochemistry, 36(23), 7136-7143 (1997-06-10)

Intramolecular isotope effects associated with the benzylic hydroxylation of a series of selectively deuterated isomeric xylenes and 4,4'-dimethylbiphenyl as catalyzed by various rat liver microsomal preparations and CYP2B1 were determined. Substrate analogs in which each methyl group contained either one

Active site characteristics of CYP4B1 probed with aromatic ligands.

K R Henne et al.

Biochemistry, 40(29), 8597-8605 (2001-07-18)

The active site topography of rabbit CYP4B1 has been studied relative to CYP2B1 and CYP102 using a variety of aromatic probe substrates. Oxidation of the prochiral substrate cumene by CYP4B1, but not CYP2B1 or CYP102, resulted in the formation of
