The direct methylation of ortho C–H bonds in aromatic amides with dicumyl peroxide (DCP) using a nickel complex as the catalyst is reported. The reaction shows a high functional group tolerance and is inhibited by radical scavengers. In reactions of meta-substituted aromatic amides, the reaction proceeds in a highly selective manner at the less hindered C–H bonds.

A protocol for the synthesis of hindered 4-aryl 2-aminopyrimidines from β–keto esters is described. The process employs trifluoroethanol as an essential additive to promote the guanidine condensation reaction, enabling the synthesis of 25 aryl- and heteroaryl substituted aminopyrimidines in good yields and high purities with no column chromatography. The conditions described herein are readily scalable

Rhodium‐Catalyzed Alkylation of C−H Bonds in Aromatic Amides with Non‐activated 1‐Alkenes: The Possible Generation of Carbene Intermediates from Alkenes
The alkylation of C−H bonds (hydroarylation) in aromatic amides with non‐activated 1‐alkenes using a rhodium catalyst and assisted by an 8‐aminoquinoline directing group is reported. The addition of a carboxylic acid is crucial for the success of this reaction. The results of deuterium‐labeling experiments indicate that one of deuterium atoms in the alkene is missing, suggesting that the reaction does
The synthesis of indanone derivatives by the Rh(III)-catalyzed reaction of α-carbonyl sulfoxonium ylides with activated alkenes is reported. The reaction shows a high tolerance for functional groups and furnishes a variety of substituted indanone derivatives via a formal [4 + 1] cycloaddition. Highly stable sulfoxonium ylides were used as substrates in this C-H functionalization, and their bifunctional
