An efficient oxidative coupling protocol for amide formation has been developed. Various tertiary amines and aromatic aldehydes were oxidized to their corresponding tertiary amides in moderate to good yields in the presence of a simple nBu4NI-catalyst.
已经开发了用于酰胺形成的有效的氧化偶联方案。在简单的n Bu 4 NI催化剂存在下,各种叔胺和芳族醛以中等到良好的收率被氧化成它们相应的叔酰胺。

KMnO4-mediated oxidative CN bond cleavage of tertiaryamines producing secondary amine was introduced, which was trapped by electrophiles (acyl chloride and sulfonyl chloride) to form amides and sulfonamides. The reaction could take place at mild condition, tolerating a wide range of function groups and affording products in moderate to excellent yields.

Substituted aromatic amides were alkylated under PTC conditions. Compounds with ortho electron withdrawing substituents furnished exclusively monoalkyl amines. A plausible mechanism has been suggested.
