Chiral-at-Metal: Iridium(III) Tetrazole Complexes With Proton-Responsive P-OH Groups for CO₂ Hydrogenation.

ABSTRACT: A rise in atmospheric CO₂ levels, following years of burning fossil fuels, has brought about increase in global temperatures and climate change due to the greenhouse effect. As such, recent efforts in addressing this problem have been directed to the use of CO₂ as a non-expensive and non-toxic single carbon, C₁, source for making chemical products. Herein, we report on the use of tetrazolyl complexes as catalyst precursors for hydrogenation of CO₂. Specifically, tetrazolyl compounds bearing P-S bonds have been synthesized with the view of using these as P^∧N bidentate tetrazolyl ligands (1-3) that can coordinate to iridium(III), thereby forming heteroatomic five-member complexes. Interestingly, reacting the P,N</
