    摘要: A hydrocarbonylation process for producing an aldehyde or a mixture of a ketone and an aldehyde which comprises:(I) forming a reaction mixture comprising:(a) a catalytic amount of a complex catalyst consisting essentially of rhodium in complex combination with:(i) a triorganophosphine, and(ii) a carboxylic acid having a phenyl group substituted at the para position with a non-reactive electron-withdrawing group, said phenyl group being free of further substitution and said electron withdrawing group being substantially non-reactive in said process;(b) an alpha-olefin having 2 to 5 carbon atoms,(c) carbon monixide, and(d) hydrogenwith the proviso that the reaction mixture has mole ratio of said carbxoylic acid to rhodium of at least about 2; and(II) maintaining the reaction mixture at a temperature and pressure at which said (b), (c) and (d) react to form an aldehyde or a mixture of an aldehyde and a ketone.

    摘要: This invention relates to a novel process for the preparation of rhodium(I) carbonyltriorganophosphorus mono-.beta.-ketoenolate complexes which comprises reacting a halocarbonylbis(triorganophosphorus) rhodium(I) complex, a .beta.-ketoenolate source and an oxygen transfer agent. The complexes so produced are useful as precursors for catalysts in hydroformylation processes.
