Aromatic ketones were synthesized via a palladiumcatalyzedcross-couplingreaction of boronic acids with acylchlorides in the presence of Na2CO3 at room temperature under solvent-free conditions. The ligand-free and mild reaction conditions, highly rapid reaction rate and good to excellent yields are important features of this method.
在室温,无溶剂条件下,在Na 2 CO 3存在下,硼酸与酰氯的钯催化交叉偶联反应合成了芳香酮。无配体和温和的反应条件,快速的反应速率以及良好至极好的收率是该方法的重要特征。

A tandem Cp*Rh(III)-catalyzed C–H activation/Brønsted acid-catalyzed intramolecular cyclization allows a facile synthesis of carbazoles from readily available indoles. The reaction proceeds under rather mild reaction conditions with the generation of water and N2 as the only byproducts. Broad substrate scope, excellent functional group tolerance, and high yields were observed. The benzannulation of
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

functionalization has enabled efficient derivatization of commercially available carbazoles in a highly site-selective manner via a unique six-membered palladacycleintermediate. This reaction boasts good functional group compatibility and displays distinct reactivities based on C3-substituents of unsymmetrical substrates.
