This study highlights the mechanistic aspects of catalyst activation and product formation and the specific role of each additive components using density functional theory calculations. The experimental and theoretical studies indicate that a Ln<span></span>N<span></span>ethylene complex (M1) is the active form of the catalyst and captures a CO₂ molecule, which reductively couples with ethylene to produce a metallalactone (M2). Conceptually, several reaction pathways can emerge from this metallalactone intermediate.

This finding contrasts with the classical notion of a β-hydride transfer to a metal. In this transformation, a Lewis acid also plays a crucial role of weakening the metal–oxygen bond, while new ethylene coordination facilitates product elimination.
