  DOI：10.1002/ejoc.201601137

  日期：2016.12

  reaction of aldehydes or ketones through a domino process involving two ensuing steps in a single pot is realized. The compatibility of Matsubara's reagent and Wilkinson's complex give a combination that allows, under dihydrogen, the transformation of a carbonyl function into a methyl group. This new method is suitable to introduce an ethyl motif from aromatic and aliphatic aldehydes with total chemoselectivity

  醛或酮的亚甲基化/加氢级联反应通过多米诺骨牌过程实现，该过程涉及两个随后的步骤在一个锅中。Matsubara 试剂和威尔金森复合物的相容性提供了一种组合，允许在二氢作用下将羰基官能团转化为甲基。这种新方法适用于从芳香族和脂肪族醛中引入乙基基序，具有总化学选择性和 α-立体化学纯度的总保留。开发的程序还扩展到从酮中引入甲基。
