Fe(0)-Catalyzed Alkyne Carboxylation with CO 2 Involving Spin Crossover

Key Points

The research aims to investigate Fe(0)-catalyzed alkyne carboxylation using CO2 and analyze the spin crossover mechanics involved.
Utilized Fe(0)-phenanthroline complexes in the reaction process.
Conducted density functional theory (DFT) calculations to explore reaction pathways.
Focused on the transition between triplet and quintet spin states.
Successfully achieved alkyne carboxylation using CO2.
DFT calculations indicate a spin crossover from triplet to quintet state during the reaction.

Abstract

The first Fe(0)-catalyzed alkyne carboxylation using CO2 is reported using Fe(0)-phenanthroline complexes, and DFT calculations suggest spin crossover from triplet to quintet along the reaction.
