Chem. Commun., 2015, Advance Article
DOI: 10.1039/C4CC10084K, CommunicationZhi-Chao Cao, Da-Gang Yu, Ru-Yi Zhu, Jiang-Bo Wei, Zhang-Jie Shi
A direct arylation to furnish diarylmethanes from benzyl alcohols was realized through Pd(PPh3)4-catalyzed Suzuki-Miyaura coupling via benzylic C-O activation in the absence of any additives. The arylation is compatible with various functional groups. This development provides an atom- and step-economic way to approach a diarylmethane scaffold under mild and environmentally benign conditions.
