Acceptorless double dehydrogenative cross-coupling of secondary and primary alcohols under nickel catalysis is reported. This Guerbet type reaction provides an atom- and a step-economical method for the C-alkylation of secondary alcohols under mild, benign conditions. A broad range of substrates including aromatic, cyclic, acyclic, and aliphatic alcohols was well tolerated. Interestingly, the C-alkylation
报道了在镍催化下仲醇和伯醇的无受体双脱氢交叉偶联。这种Guerbet型反应为温和,良性条件下仲醇的C-烷基化提供了一种原子经济和分步经济的方法。包括芳香族,环状,无环和脂肪族醇在内的多种底物均具有良好的耐受性。有趣的是,还证明了胆固醇衍生物的C-烷基化和环戊醇与各种醇的双C-烷基化。
