The first iron-catalyzed formal cross coupling of homobenzylic methyl ethers with alkyl Grignardreagents is realized. The reaction is proposed to proceed through a sequence of dehydroalkoxylation to form the vinyl-intermediate, followed by Fe-catalyzed selective carbometalation to form a benzylic Grignardreagent.

A novel copper-catalyzedarylation of benzylic C-H bonds with nucleophilic arylboronic acids has been developed that provides an efficient way to synthesize various 1,1-diarylalkanes with a broad substrate scope and excellent functional group compatibility. The reactions occur at room temperature using alkylarenes as the limiting reagents, which allows access to the arylation of the more valuable and
