چکیده انگلیسی
The mechanism for hydrogenation of dimethylmaleate in water using cationic rhodium complexes with water-soluble bi-dentate phosphines has been investigated using kinetics and a novel method for the indirect detection of intermediates in catalytic hydrogenation reactions, whereby a late intermediate was detected. A mechanism is proposed involving fast, irreversible substrate binding followed by a rate-determining reaction with dihydrogen.
The kinetics of rhodium cation catalysed hydrogenation of dimethylmaleate was investigated in water, and to detect intermediates a new para-hydrogen-based technique was used giving indirectly detected 1H NMR spectra.Figure optionsDownload as PowerPoint slide
