Article abstract of DOI:10.1246/bcsj.54.2829

In order to determine the mechanism of 2,2'-diaminobiphenyl formation from benzocinnoline, 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-dihydrobenzocinnoline, and that the resulting adduct participated in the subsequent photo-induced 2,2'-diaminobiphenyl formation.
