present a redox-neutral method for the photocatalytic generation of carbanions. Benzylic carboxylates are photooxidized by single electron transfer; immediate CO2 extrusion and reduction of the in situ formed radical yields a carbanion capable of reacting with aliphatic aldehydes as electrophiles giving the Grignard analogous reaction product.
我们提出了一种用于光催化产生碳负离子的氧化还原中性方法。苄基羧酸盐通过单电子转移被光氧化;立即CO 2挤出和原位形成的自由基的还原产生能够与作为亲电试剂的脂肪醛反应的碳负离子,从而产生格氏类似反应产物。
