Pd0 catalysts featuring phosphorus-based monodentate ligands was detour the reactivity of carbonyl-tethered alkylidenecyclopropanes (ACPs) from standard (3+2) cycloadditions towards tandem cycloisomerization/cross-coupling processes. This new reactivity lies on the formation of key π-allyl oxapalladacyclic intermediates, which were subsequently trapped with external nucleophilic partners, instead of undergoing canonical C-O reductive eliminations. Importantly, the use of imine-tethered ACP’s was also feasible. Therefore, the method provided a straightforward and stereoselective entry to a wide variety of highly functionalized cyclic alcs. and amines.
