Abstract
Immobilized rhodium and iridium complexes have been prepared and characterized by X-ray photoelectron spectroscopy. For the first time, hyperpolarized 13C-ethylene was detected directly in the gas phase during acetylene hydrogenation with parahydrogen over immobilized iridium complexes. The line shape of polarized 13С‑ethylene unambiguously indicates that the hydrogen addition to the triple bond of acetylene over immobilized iridium complexes proceeds stereoselectively via syn-addition. It has been shown that the selective acetylene hydrogenation with parahydrogen over immobilized iridium complexes is an efficient chemical method for enriching the nuclear spin isomers of ethylene.
