Reductive deoxygenation of alcohols is particularly challenging because of the high bond dissociation energy of the C-OH bond and the poor leaving ability of the hydroxyl group. Herein we describe a PhP═O-catalyzed reductive deoxygenation of benzyl alcohols with PhSiH under an air atmosphere within 30 min of reaction time. The use of catalytic loading of PhP═O enhances the practicality of this protocol.
由于C-OH键的高键解离能以及羟基较差的离去能力，醇的还原脱氧特别具有挑战性。在此，我们描述了在空气气氛下，在30分钟的反应时间内，PhP═O催化苄醇与PhSiH进行还原脱氧反应。使用PhP═O的催化负载量提高了该方法的实用性。
