A mild and efficient procedure for the silver-catalyzed tandem trifluoromethylation and cyclization of aryl isonitriles with the Langlois reagent (sodium triflinate) is developed. A series of trifluoromethylated phenanthridines is prepared in moderate to good yields from a cheap and stable trifluoromethyl source.

A visible-light-induced tandem radical addition-cyclization sequence via 2-aryl phenyl isocyanides as the starting material and two-dimensional covalent organic frameworks (2D-COFs) as the photocatalyst was developed, delivering multifarious 6-substituted phenanthridines in high yields. Benefitting from the utilization of a heterogeneous photocatalyst, this protocol features easy catalyst separation and excellent recyclability. A negligible loss of the catalytic activity was observed after multiple runs. High practicability of this protocol was further demonstrated by continuous flow experiments.
Transition Metal-Free Oxidative Radical Decarboxylation/Cyclization for the Construction of 6-Alkyl/Aryl Phenanthridines

, p. 9336 - 9341 (2015/09/28)
A radical cascade decarboxylation/cyclization of 2-isocyanobiphenyls with aliphatic carboxylic acids as well as aromatic carboxylic acids under the transition metal-free conditions was reported. This process, which included formation of two new C-C bonds and cleavage of C-COOH bonds, afforded a novel and environmentally friendly approach to producing 6-alkyl/aryl phenanthridines with moderate to good yields.
