A process for preparing a variety of secondary and tertiary alkyl formate esters via the coupling of methanol and secondary (or tertiary) alcohols. Iron-based catalysts, supported by pincer ligands, are employed to produce these formate esters in high yields and unprecedentedly high selectivities (>99%). Remarkably, the coupling strategy is also applicable to bulkier tertiary alcohols, which afford corresponding tertiary formate esters in moderately high yields and high selectivities.
一种通过甲醇和仲醇(或叔醇)偶联制备各种仲烷基和叔烷基甲酸酯的工艺。铁基催化剂在钳形配体的支持下,以高产率和前所未有的高选择性(大于 99%)制备这些甲酸酯。值得注意的是,这种偶联策略也适用于体积较大的叔醇,它们能以中等高产率和高选择性生成相应的甲酸叔酯。
