δ-carbonylation of saturated alcohols which uses a 1,5-hydrogen-transfer reaction of alkoxyl radicals and subsequent carbonylation at the δ-carbon atoms as the key. The carbonylation reactions of five classes of saturated alcohols, namely, primary alcohols having primary δ-carbons, primary alcohols having secondary δ-carbons, primary alcohols having tertiary δ-carbons, secondary alcohols having primary δ-carbons
本文描述了饱和醇的 δ-羰基化反应,它以烷氧基的 1,5-氢转移反应和随后在 δ-碳原子上的羰基化反应为关键。5类饱和醇的羰基化反应,即具有伯δ-碳的伯醇、具有仲δ-碳的伯醇、具有叔δ-碳的伯醇、具有伯δ-碳的仲醇、具有仲δ-碳的仲醇进行了碳,其中四乙酸铅(LTA)用作单电子氧化剂以产生烷氧基自由基。除了具有叔 δ-碳的伯醇外,这些饱和醇的羰基化以中等至良好的产率得到 δ-内酯。
