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.

temperature deoxygenation of both aromatic and aliphaticcarboxylic esters to ethers has been achieved by regulating the stoichiometry of the reductant, BH3–NH3, and the catalyst, TiCl4. This first, practical borane-mediated process is compatible with various potentially sensitive functional groups and is applicable to the deoxygenative ether formation from typically challenging aromaticacid esters. Substituting
