-Catalyzed Highly Selective Dehydrogenative Coupling of Alcohols and Cyclohexenones
synthesis of aryl alkyl ethers has been described. DMSO is employed as the mild terminal oxidant. This novel methodology offers a metal‐free reaction condition, operational simplicity and broad substrate scope to afford valuable products from inexpensive reagents. Various meta‐substituted aromatic ethers which are hardly synthesized from the reported methods requiring meta‐substituted phenols, are efficiently

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.
