Studies on the Selective Intramolecular Biaryl Coupling Reaction of 2-Triflyloxy-6-halobenzanilides Using a Palladium Reagent
摘要:
The aryl-aryl coupling reaction of 2-triflyloxy-6-halobenzanilides using a palladium reagent under several reaction conditions was examined. The 6-iodo compound gave triflyloxyphenanthridone selectively in excellent yield under the conditions for the ordinary Heck reaction.

A divergent reaction of isocyanides with o-bromobenzaldehydes for the synthesis of isoindolinone-derived ketenimines and lactams was disclosed. The reaction features readily available reactants, relatively mild conditions, and high yields of products. Ketenimines could be applied in further transformations for access to other functional molecules. A mechanism study showed that the palladium-migration/imine-insertion
