amide is established to be an effective catalyst system for Goldberg amidation with inferior reactive (hetero)aryl chlorides, which have not been efficiently documented by Cu-catalysis to date. The reaction is well liberalized toward a variety of functionalized (hetero)aryl chlorides and a wide range of aromatic and aliphatic primary amides in good to excellent yields. Furthermore, the arylation of

A versatile new synthesis of quinolines and related fused pyridines. Part 8. Conversion of anilides into 3-substituted quinolines and into quinoxalines
3-substituted quinolines (7). When N-nitrosodialkylamines are used in place of dimethylformamide as the Vilsmeier agent, the anilides are converted into 2-chloroquinoxalines in low yields. Several by-products are formed and the mechanisms have been explored. Thus, the formation of ethyl N-arylcabamate from the corresponding propionanilide is shown to involve an C→O alkyl migration related to a Wolff rearrangement
