example of the palladium-catalyzed tandem addition/cyclization of 2-(2-acylphenoxy)acetonitriles with arylboronic acids has been developed, providing a new strategy for the synthesis of 2-aroyl benzofurans with excellent chemoselectivity and wide functional group compatibility. Preliminary mechanistic experiments indicate that this tandem process involves sequential nucleophilic addition generating 2
been developed for the synthesis of 2‐aroylindoles (3a, 3b, 3c, 3d, 3e, 3f, 3g, 3h, 3i, 3j) in good yields by the reaction of 2‐aminoketones (1a, 1b, 1c) with phenacyl bromides (2a, 2b, 2c, 2d). The reaction success varied with different bases and solvents in both conventional and microwave methods. But finally, it was established that piperidine in DMF was an effectivemedium to carry out the reaction
