| Abstract: | The carbon monoxide uptake in the reaction of allylbenzene with CoH(CO)4 in n-octane leading to acylcobalt tetracarbonyls and aldehydes is catalyzed by Co2(CO)8. The rate is half order in Co2(CO)8, first order in allylbenzene and shows a complex dependence in CoH(CO)4 and CO. From kinetic experiments between 15 and 45° C the temperature dependence of the observed rate constant was determined. The complete analogy of this kinetics with that obtained for heptene-1 shows that the main aldehydic product 2-phenylbutyraldehyde is formed by a mechanism characteristic for aliphatic olefins and not by one operative for styrenes. |
