We describe herein the intermolecular addition reaction of benzyl halides to aldehydes and imines using photoactivated tetrakis(dimethylamino)ethylene (TDAE) as superphotoreductant. 3,4-Dihydroisocoumarins, 1,2-diarylethanols, and 1,2-diarylcarbamates were obtained with good functional group tolerance using simple, mild, and metal-free conditions.
我们在此描述了使用光活化四(二甲氨基) 乙烯 (TDAE) 作为超光还原剂的苄基卤化物与醛和亚胺的分子间加成反应。3,4-二氢异香豆素、1,2-二芳基乙醇和1,2-二芳基氨基甲酸酯在简单、温和和无金属条件下获得了良好的官能团耐受性。
