SBA-15-functionalized melamine-pyridine group-supported palladium(0) was found to serve as a heterogeneous and recyclable nanocatalyst for N-arylation of indoles with aryl iodides under a low catalyst loading (0.3mol% of Pd) through Ullmann-type C￡N coupling reactions. A variety of aryl iodides could be aminated to provide the N-arylated products in good to excellent yields without the need of an inert atmosphere. Also, this catalyst was found to be an efficient system for the N-arylation of other nitrogen-containing heterocycles with aryl iodides. The heterogeneous palladium catalyst could be recovered by simple filtration of the reaction solution and reused for six cycles without significant loss in its activity.

N-arylation of indoles with aryl halides using copper/glycerol as a mild and highly efficient recyclable catalytic system
Yadav, Dilip Kumar T.,Rajak, Sanil S.,Bhanage, Bhalchandra M.
, p. 931 - 935 (2014/02/14)
A simple, efficient, and inexpensive copper catalyzed protocol has been developed for cross-coupling of indoles with aryl halides by using glycerol as a green recyclable solvent and DMSO as an additive. The reaction was carried out at low catalyst loading furnishing various N-aryl indoles in good to excellent yield. This copper/glycerol mixture was recycled up to four runs without any loss in its catalytic activity.

Palladium-catalyzed sonogashira-coupling conjoined C-H activation: A regioselective tandem strategy to access indolo- and pyrrolo[1,2- a ]quinolines

, p. 10382 - 10392 (2013/01/15)
An operationally simple approach for the regioselective tandem synthesis of indolo[1,2-a]quinolines 4a-v and pyrrolo[1,2-a]quinolines 5a-k from 1-(2-bromophenyl)-1H-indole/pyrrole/imidazole 1a-c, 2a,b by the palladium-catalyzed sequential C-C bond formation is described. The developed approach involves the palladium-catalyzed Sonogashira coupling followed by the intramolecular C-C bond formation via C-H activation, which leads to the formation of 6-endo-dig cyclized product. This synthetic methodology accommodates wide functional group variation on alkyne, which proves to be advantageous for the structural and biological activity assessments.
