| Abstract: | Electron-poor alkenes such as alkyl acrylates have been found to insert into the aromatic carbon—palladium bond in orthobromobenzamides under the conditions of the Heck reaction. For primary and secondary benzamides a further palladium-catalysed reaction occurs to yield 3-substituted, or 2,3-disubstituted phthalimidines. |
