hydroperoxidatedcarbonyl compounds derived from the Michael reaction of 5,5-dimethylcyclohexane-1,3-dioneand chalcone, is reported. A series of aromatic acylsilanes withTBDPS were obtained in promising isolated yields. In addition, asan extension of the relay oxidation under aerobic conditions, thiscatalyst-free relay oxidation induced by diketone can be appliedto the oxidation of general aromatic alcohols
在这封信中,报告了一个有趣的 α-羟基硅烷无金属中继空气氧化的例子,该反应由源自 5,5-二甲基环己烷-1,3-二酮和查耳酮的迈克尔反应的氢过氧化羰基化合物促进。以有希望的分离产率获得了一系列具有 TBDPS 的芳族酰基硅烷。此外,作为有氧条件下中继氧化的延伸,这种由二酮诱导的无催化剂中继氧化可应用于一般芳香醇的氧化(产率高达75%)。
