Visible light, in combination with the molecular iodine catalyst-mediated α-hydroxylation of α-methylene ketones, has been developed. The reaction proceeds smoothly in methanol at room temperature under aerobic conditions and shows exclusive selectivity toward methylene ketones. Mechanistic studies have revealed that the reaction proceeds by a radical pathway. Renewable energy, metal-free catalyst and abundant oxygen source alongside a wide scope and novel selectivity are features that make this strategy practical and eco-friendly.

有氧条件下可见光介导的碘催化的α-亚甲基酮的α-羟基化†

已经开发了可见光，与分子碘催化剂介导的α-亚甲基酮的α-羟基化作用相结合。该反应在室温下在有氧条件下于甲醇中平稳进行，并显示出对亚甲基酮的唯一选择性。机理研究表明，该反应通过自由基途径进行。可再生能源，无金属催化剂和丰富的氧气源以及广泛的选择性和新颖的选择性是使该策略切实可行和生态友好的特征。
