Unactivated α-branched primary and secondary aliphatic alcohols have been successfully transformed into their corresponding alkyl chlorides in high yields upon treatment with a mixture of triphosgene and pyridine in dichloromethane at reflux. These mild chlorination conditions are high yielding, stereospecific, and well tolerated by numerous sensitive functionalities. Furthermore, no nuisance waste
在回流的二氯甲烷中用三光气和吡啶的混合物处理后,未活化的α-支化伯和仲脂肪醇已成功转化为相应的烷基氯化物,产率高。这些温和的氯化条件具有高产量、立体特异性,并且对许多敏感功能具有良好的耐受性。此外,在反应过程中不会产生有害废物。
