[Ru(PhCOO)(CO)2(PhCOOH)]2, the catalyst, indicates that the active catalytic species are mononuclear rutheniumcomplexes. A stoichiometric reaction modelled on the catalytic reaction was monitored by infrared spectroscopy and finally quenched with PPh3. The quenching products were identified as new mononuclear rutheniumcomplexes, and these identifications greatly facilitated understanding of the mechanism leading

Preparation of enols: When treated with [Pd(cinnamyl)Cl}2]/cataCXium A (nBuPAd2, Ad=adamantyl) under an atmosphere of CO, arylketones react with aryl halides in a carbonylative CO coupling reaction to form (Z)‐vinyl benzoates (see scheme).
