sulfides bearing a tetrafluoropyridinyl group with bis(catecholato)diboron followed by treatment with pinacol and triethylamine affording pinacol boronic esters is described. The reaction is promoted by an organic photocatalyst (3DPA2FBN) under irradiation with 400 nm light, and works with primary, secondary, and tertiary sulfides. The electron depleting character of the fluorinated pyridine fragment
描述了带有四氟吡啶基的硫化物与双(邻苯二酚)二硼的相互作用,然后用频哪醇和三乙胺处理,得到频哪醇硼酸酯。有机光催化剂(3DPA2FBN)在400 nm光的照射下促进了该反应,并与伯,仲和叔硫化物一起起作用。氟化吡啶片段的电子消耗特性在产生烷基中起重要作用。
