Diboron-mediated rhodium-catalyzed transfer hydrogenation of functionalized arenes is reported. In addition to good functional group tolerance, the reaction features operational simplicity and controllable chemoselectivity. The general applicability of this procedure is demonstrated by the selective hydrogenation of a range of arenes, including functionalized benzenes, biphenyls, and polyaromatics.

Paragraph 0127-0133, (2021/11/21)
The invention discloses an aryl or heteroaryl methoxylation reaction method. The method comprises the following steps: preparing a substrate. The coupling agent, ligand, solvent, catalyst and base are mixed homogeneously in an inert gas to give the aryl or heteroaryl methoxy compounds. Compared with a methoxylation reaction method in the prior art, the method has the advantages that the reaction system conditions are mild, the usage amount of the catalyst and the ligand is low to 5% of the amount of the substrate material, and the catalytic efficiency is improved. The method has better compatibility to different substrate expansion and discovery of aryl halides or heteroaryl halides with different functional groups. The yield of aryl or heteroaryl methoxy compounds prepared by the method disclosed by the invention is 36% - 89%.

A Cu-catalyzed cross-coupling reaction between aryl bromides and 9-BBN-OMe to provide aryl methyl ethers under mild conditions is reported. The oxalamide ligand BHMPO plays a key role in the transformation. Various functional groups on bromobenzenes are well tolerated, providing the desired anisole products in moderate to high yields.
