We describe here the facile construction of sterically hindered tertiary alkyl ethers and thioethers via the Zn(OTf)2-catalyzed coupling of alcohols/phenols with unactivated tertiary alkyl bromides and the Cu(OTf)2-catalyzed thiolation of unactivated tertiary alkyloxalates with thiols. The present protocol represents one of the most effective unactivated tertiary C(sp3)–heteroatom bond-forming conditions
