摘要
在二碘化钐、钐和镍组合的促进下，开发出了一种酮与硼氢烷酯的直接脱氧硼氢化反应。在这种方法中，硼酸烷基酯与硼酸氢酯一步就能从未激活的酮中合成出硼酸烷基酯。该方法具有广泛的底物范围和对 CO 裂解的出色选择性。这种方法代表了一种从未激活的酮中合成多功能仲烷基硼酸酯的通用方法。
Samarium diiodide/samarium-mediated direct deoxygenative hydroborylation of ketones with hydroborane esters†
A direct deoxygenative hydroborylation of ketones with hydroborane ester promoted by a combination of samarium diiodide, samarium and nickel has been developed. In this method, secondary alkyl borate esters are synthesized from unactivated ketones with hydroborane esters in one step. A broad substrate scope and excellent selectivity toward CO cleavage has been demonstrated. This approach represents a general method for the construction of versatile secondary alkyl borate esters from unactivated ketones.
