In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Rhodium(III)-Catalyzed Direct Coupling of Quinoline-8-Carbaldehydes with (Het)Arylboronic Acids for the Synthesis of 8-Aryloylquinolines, published in 2020-08-07, which mentions a compound: 178396-31-1, mainly applied to aryl heteroaryl ketone synthesis; rhodium catalyzed coupling quinolinecarboxaldehyde aryl heteroaryl boronic acid; tubulin polymerization inhibitor synthesis, Recommanded Product: 178396-31-1.

Herein, we describe a method for the synthesis of aryl-(het)aryl ketones by Rh(III)-catalyzed direct coupling between quinoline-8-carbaldehydes and (het)arylboronic acids. The method has a broad substrate scope, a high functional group tolerance, and uses com. available starting materials. Scale-up of the reaction and subsequent synthesis of tubulin polymerization inhibitor demonstrated its utilities. A plausible mechanism was proposed on the basis of the fact that a stable cycloacylrhodium intermediate complex could be used as catalyst, and the complex reacted stoichiometrically with (het)arylboronic acids.
