A simple method has been developed for the reductive deoxygenation of aromatic ketones and benzylic alcohols in the presence of polymethylhydrosiloxane (PMHS). The reductive deoxygenation of aromatic ketones and benzylic alcohols, including secondary alcohols, to the corresponding methylene hydrocarbons has been achieved in good to excellent yields using palladium chloride (PdCl2) as catalyst and PMHS
                                    已经开发出一种简单的方法,用于在聚甲基氢
硅氧烷(PMHS)存在下对芳族酮和
苄醇进行还原性脱氧。使用
氯化钯(PdCl 2)作为催化剂,以PMHS作为
氢化物源,可以很好地实现芳族酮和
苄醇(包括仲醇)到相应的亚甲基烃的还原脱氧。用芳基烷基酮和二芳基酮成功地进行了这种脱氧,例如分别通过对
苯乙酮和
二苯甲酮的还原性脱氧来说明。相应的
苯甲醇和仲
醇类似物也可以通过PdCl 2 / PMHS系统转化成它们各自的亚甲基烃。
