[RuII(tpy)(bpy)Cl]+-Catalyzed reduction of carbon dioxide. Mechanistic insights by carbon-13 kinetic isotope effects

Abstract

In this work, we examine the use of competitive ¹³C kinetic isotope effects (¹³C KIEs) on CO₂ reduction reactions that produce CO and formic acid as a means to formulate reaction mechanisms. The findings reported here mark a further advancement in the combined ¹³C KIE measurements and theoretical calculations methodology for probing CO₂ conversion reactions.
