A visible-light-induced synthesis of N-H carbazoles from easily accessible 2,2′-diaminobiaryls in the absence of any external photosensitizer is reported. The process only requires tBuONO and natural resources, visible light, and molecular oxygen for the synthesis of N-H carbazoles. Experimental and computational studies support that the in situ formation of a visible-light-absorbing photosensitizing
据报道,在没有任何外部光敏剂的情况下,可见光诱导了从易于获得的2,2'-二氨基联芳基合成N -H咔唑。该方法仅需要t BuONO和自然资源,可见光和分子氧即可合成N -H咔唑。实验和计算研究支持原位形成吸收可见光的光敏中间产物苯并cinlineline N-酰亚胺负责将三线态分子氧活化为单线态氧,进而促进咔唑的合成。
