Method for selective N-methylation of secondary amide

The invention relates to a method for selective N-methylation of secondary amide. The method is characterized in that the secondary amide is in an organic solvent N, N-dimethyl formamide or dimethyl sulfoxide, trifluoroacetic acid methyl ester serves as a methylation reagent, and reaction is performed in the presence of sodium hydride, potassium tert-butoxide or sodium methylate, so as to obtain aselective N-methylated product. The method has the characteristics that generally a trifluoroacetylation product is produced when the trifluoroacetic acid methyl ester is reacted with amine compounds, however a N-methylated product can be selectively obtained when the trifluoroacetic acid methyl ester is reacted with secondary amide; the method is simple to operate, low in cost, mild in reactionconditions and high in selectivity, and avoids the use of hypertoxic methylation reagents, such as dimethyl sulfate and methyl iodide.

Amide Effects in C?H Activation: Noncovalent Interactions with L-Shaped Ligand for meta Borylation of Aromatic Amides

A new concept for the meta-selective borylation of aromatic amides is described. It has been demonstrated that while esters gave para borylations, amides lead to meta borylations. For achieving high meta selectivity, an L-shaped bifunctional ligand has been employed and engages in an O???K noncovalent interaction with the oxygen atom of the moderately distorted amide carbonyl group. This interaction provides exceptional control for meta C?H activation/borylation.
