A palladium-catalyzed reaction sequence consisting of an intermolecular amination and an intramolecular direct arylation enabled highly regioselective syntheses of functionalized indoles or carbazoles and proved to be amenable to the use of inexpensive 1,2-dichloroarenes as electrophiles. arylation - catalysis - heterocycles - palladium - sequential reaction

For the first time TFAA/H3PO4 has facilitated the direct and metal-free N-acylation of carbazoles leading to a number of N-acylated derivatives. Several of these compounds were found to be promising when tested for their anti-proliferative properties against oral cancer cell lines.
The synthesis of 1- and 3-aroylcarbazoles has been achieved by the photolysis of N-aroylcarbazoles alongwith the formation of carbazole and the rearranged product ratio is wavelength dependent.

The synthesis of 3-aroylcarbazoles [(a-d)] and the unknown 1-aroylcarbazoles [(a-c)] been achieved by the photolysis of 9-aroylcarbazoles [(a-d)] in polar solvent. Irradiation of (a-c) in non-polar solvent afforded regiospecifically (a-c), carbazole () and for the first time, 9H-indolo [3, 2, 1-de] phenanthridin-9-one () from b. The yield of was significantly improved by UV exposure of 9-(2-iodobenzoyl)-carbazole
