Abstract

Intermolecular insertion: A palladium-catalyzed domino aminopalladation/ C[BOND]H functionalization sequence has been developed, and provides access to functionalized phenanthridines and isoquinolines (see scheme; Tf=triflate, TMS=trimethylsilyl, M.S.=molecular sieves). The use of butyronitrile as the solvent is determinant to the success of the domino process.
