The palladium(II)-catalyzed, intramol. alkene hydrofunctionalization reactions with carbon, nitrogen, and oxygen nucleophiles formed five- and six-membered carbo- and heterocycles. In these reactions, the presence of a proximal bidentate directing group controlled the cyclization pathway, dictating the ring size that was generated, even in cases that are disfavored based on Baldwin’s rules and in cases where there is an inherent preference for an alternative pathway. DFT studied shed light on the origins of pathway selectivity in these processes.
