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.
