to determine the mechanism of 2,2′-diaminobiphenyl formation from benzo[c]cinnoline, effect of aldehyde on the reaction was examined. It is proposed that ethanal, which was generated from ethanol in the initial photoreduction, formed an adduct with 5,6-dihydrobenzo[c]cinnoline, and that the resulting adduct participated in the subsequent photo-induced 2,2′-diaminobiphenyl formation.
为了确定苯并[c]肉啉形成 2,2'-二氨基联苯的机理,研究了醛对反应的影响。提出在初始光还原中由乙醇生成的乙醛与 5,6-二氢苯并 [c] 肉啉形成加合物,并且所得加合物参与了随后的光诱导 2,2'-二氨基联苯的形成。
