A Reformatsky-type reaction has been developed using iron catalysis in acetonitrile or DMF. Reduction of iron(II) bromide by manganese metal in acetonitrile provides a low-valent iron catalyst, which is the active species; under these conditions, α-chloroesters or nitriles can both be converted into their corresponding derivatives. The method was applicable to both ketones and aldehydes, resulting in the formation of β-hydroxyesters under mild conditions.
一种 Reformatsky 型反应已采用铁催化体系在乙腈或二甲基甲酰胺中得到开发。通过在乙腈中用锰金属还原二溴化铁,可得到低价铁催化剂,该催化剂为活性物种;在这些条件下,α-氯酯或腈均可转化为相应的衍生物。该方法适用于酮和醛,在温和条件下形成 β-羟基酯。
