TL;DR: A mild and efficient method for the synthesis of 6-(trifluoromethyl)phenanthridines through oxidative cyclization of 2-isocyanobiphenyls with CF3SiMe3 under metal-free conditions was developed.

TL;DR: In this paper, it was shown that hydrazines with visible-light in the presence of organic dye eosin B generate various types of functional radicals, which are trapped by 2-isocyanobiphenyls to give 6-substituted phenanthridines.

TL;DR: The first visible-light induced cross-dehydrogenative coupling between tertiary amines and diazo compounds is described, successfully employed for the synthesis of 4- or 5-ester N-aryl-2,3-dihydrobenzo[d]azepines with high regioselectivity simply switched by the selection of the transition metal catalysts.

TL;DR: A visible-light photoredox synthesis of 3-acylindoles through intramolecular oxidative cyclization of o-alkynylated N,N-dialkylamines is developed and a plausible mechanism involving the addition of α-amino alkyl radicals to alkynes, followed by C-O bond formation is proposed.

TL;DR: This account summarizes the synthesis of N- heterocycles using visible-light photoredox catalysis published in the last two years, according to the size and type of the formed N-heterocyclic rings.
