A palladium-catalyzedaminocarbonylation of aryl boronic acids with nitroarenes for the synthesis of amides has been developed. A wide range of substrates were well-tolerated and gave the corresponding amides in moderate to good yields. No external oxidant or reductant was needed in this procedure. This procedure provides a redox-economical process for the synthesis of amides.
The present invention relates to organic molecules capable of modulating tyrosine kinase signal transduction in order to regulate, modulate and/or inhibit abnormal cell proliferation.

Herein we describe an alternative and unconventional approach of an aminocarbonylation reaction to access aryl amides from readily available and low-cost arylboronic acids and nitroarenes. Nickel metal can serve as both reductant and catalyst in this direct aminocarbonylation. This protocol exhibits a good functional group compatibility and allows a variety of aryl amides to be synthesized, including
A general and effective method for the synthesis of amides through decarboxylative amidation of α-keto acids with amines has been developed. The reaction proceeded smoothly to afford the corresponding amide products in good yield under air and shows excellent functional group tolerance. In addition, the protocol can be further applied in the synthesis of heterocyclic compounds like benzimidazoles.

and we confirmed that it is consistent with Ni K-edge EXAFS. The Suzuki–Miyaura-type coupling of aryl halides and arylboronicesters proceeded using P4VP-NiCl2 (0.1 mol % Ni) to give the corresponding biaryl compounds in up to 94% yield. Surprisingly, when the same reaction of aryl halides and arylboronicacid/ester was carried out in the presence of amides, the amidation proceeded predominantly to
