文摘

We disclose the results of detailed catalytic and structural investigations on the reaction of propargylic alcohol with TpPPh3(HNCPh2)RuCl. A number of new ruthenium complexes have been prepared. A plausible reaction mechanism is proposed on the basis of ruthenium vinyl and formyl intermediates. Their structures are elucidated by IR, NMR and X-ray crystallography.
