✦ Synopsis

The interaction of the supported catalyst based on the organic nickel chelate compound I with carbon monoxide and Ž . deuterated ethylene has been studied using IRS-DS. The surface nickel compound SNC interacts with carbon monoxide in Ž .

Ž . the same manner as the initial nickel complex I . The reaction of SNC or nickel complex I with CO yields nickel acyl Ž . Ž . Ž . Ž . complex V a product of the CO insertion into the Ni-Ph bond , ester VIII and various nickel carbonyls VI . According to the IRS data, the interaction between SNC and deuterated ethylene gives a polymer. The subsequent carbon monoxide introduction results in the same products as in the case of the CO reaction with SNC. The interaction between ethylene and SNC pretreated with carbon monoxide does not lead to polymerization.
