A palladium catalytic system is reported for the divergent tandem cycloisomerization and cross-coupling of carbonyl- and imine-tethered alkylidenecyclopropanes (ACPs). The selection of ancillary ligands is pivotal for the interception of the heteropalladacyclic intermediates with different external nucleophiles.
