The inventive subject matter relates to novel processes for making an epoxy alcohol from an aldehyde, comprising the steps of: (a) adding (i) an organozinc compound or (ii) divinylzinc compound and an diorganozinc compound to said aldehyde in the presence of a first catalyst to form an allylic alkoxide compound; and (b) epoxidizing said allylic alkoxide compound in the presence of an oxidant and a second catalyst.
本发明涉及一种从醛制备环氧醇的新工艺,包括以下步骤:(a)在第一催化剂的存在下向所述醛中加入(i)有机锌化合物或(ii)二乙烯基锌化合物和二有机锌化合物,以形成烯丙氧化物化合物;(b)在氧化剂和第二催化剂的存在下使烯丙氧化物化合物环氧化。
