Harnessing alkaline-earth metal reactivity: mechanistic insights into alkene and alkyne functionalization <i>via</i> organomagnesium( <scp>ii</scp> ) and organobarium( <scp>ii</scp> ) catalysis

A comprehensive in silico exploration establishes fundamental understanding for alkaline-earth catalysis, proving these earth-abundant metals can function as transition-metal mimics with complementary reactivities in migratory insertion reactions.
