    • A method for preparing acetic acid and/or methyl acetate by simultaneous isomerization and carbonylation reactions. A reaction mixture is provided containing at least one reagent which provides formyl radicals and at least one further reagent which provides methyl radicals, together with water in an amount of at most 5% by weight, carbon monoxide at a partial pressure between 0.1·105 Pa and 25·105 Pa, a solvent and a catalytic system which contains at least one halogenated promoter and at least one iridium-based compound. In a typical reaction mixture, methyl formate is isomerized to form acetic acid according to the reaction: HCOOCH3CH3COOH while methanol undergoes carbonylation to form acetic acid according to the reaction: CH3OH+COCH3COOH The reagent which provides the formyl radicals is kept at or below 20% by weight of the reaction mixture, while the molar ratio of methyl radicals to formyl radicals in the mixture is greater than 1.

    • Butadiene or derivative thereof is selectively hydroxycarbonylated into at least one pentenoic acid (the pentenoic acids are themselves facilely converted, via hydroxycarbonylation, into adipic acid, a basic starting material for the production of nylon 66 polymers), by reacting same with carbon monoxide and water, at a pressure greater than atmospheric, in the presence of a catalytically effective amount of (1) a palladium catalyst which is soluble in the medium of reaction and (2) crotyl chloride, the amount of the crotyl chloride being at least two mol thereof per mole of palladium values and said palladium values/crotyl chloride at least in part comprising a palladium/crotyl pi-complex, and the amount of water present in the medium of reaction being no greater than about 20% by weight thereof.
