A mechanistically distinctive visible-light-promoted metal-free aerobic oxidation of alkenyl silanes with alcohols was disclosed to efficiently construct α-alkoxy ketones under mild conditions. The primary, secondary, and tertiary alcohols could be used as reactants. The protocol could be carried out on a gram-scale. Various derivatizations of products could be conducted. Mechanistic studies indicated
揭示了一种机制上独特的可见光促进的烯基硅烷与醇的无金属有氧氧化,可在温和条件下有效地构建α-烷氧基酮。伯醇、仲醇和叔醇可用作反应物。该协议可以在克级上执行。可以进行各种产品的衍生化。机理研究表明,该反应是由烯基硅烷的单电子氧化引发的,而不是烯基硅烷的自由基加成。
