The double N-arylation of primary amines with 2,2'-biphenylylene ditriflates was investigated for the synthesis of multisubstituted carbazoles. Palladium complexes supported by 2-dicyclohexylphosphino-2'-methylbiphenyl or Xantphos [4,5-bis(diphenylphosphino)-9,9-dimethylxanthene] were found to be efficient catalysts for the reaction. The catalysts allow the use of
The neolignans, magnolol 1 and honokiol 2 have been reported to inhibit the growth of several tumor cell lines in vitro and in vivo. The chemical structure of magnolol and honokiol consists of biphenyl skeleton with phenolic and allylic functionalities.

1. 14C-Phenol was metabolized by rat bone marrow homogenate and H2O2. The homogenate catalyst, however, was inactivated by preincubation with H2O2, presumably due to inactivation of the enzyme(s) involved in phenol metabolism. 2. The majority of the metabolized 14C-phenol was
Facile nucleophilic substitution of two chlorine atoms by 2,2'-biphenol at one of the two bay areas (1,12- and 6,7-positions) of core-tetrachlorinated perylene bisimide afforded a novel, completely desymmetrized perylene bisimide building block, which could be further functionalized by substitution of

User-friendly protocols for the protecting group-free synthesis of 2,2'-biphenols via Suzuki-Miyaura coupling of o-halophenols and o-boronophenol are presented. The reactions proceed in water in the presence of simple additives such as K2CO3, KOH, KF, or TBAF and with commercially available
