    摘要: This invention relates to processes for producing one or more substituted or unsubstituted 1,6-hexanediols, e.g., 1,6-hexanediol, which comprise subjecting one or more substituted or unsubstituted alkadienes to hydrocarbonylation in the presence of a hydrocarbonylation catalyst, e.g., a metal-organophosphorus ligand complex catalyst, and a promoter and optionally free ligand to produce said one or more substituted or unsubstituted 1,6-hexanediols. The substituted and unsubstituted 1,6-hexanediols produced by the processes of this invention can undergo further reaction(s) to afford desired derivatives thereof, e.g., epsilon caprolactone. This invention also relates in part to reaction mixtures containing one or more substituted or unsubstituted 1,6-hexanediols as principal product(s) of reaction.

    摘要: This invention relates to a process for preparing specific substituted benzaldehydes through the reaction of substituted benzenes with carbon monoxide and aluminum chloride at a relatively low pressure, at a low temperature, and in the presence of at most a catalytic amount of an acid (preferably aqueous HCl). The resultant substituted benzaldehydes are useful as precursors to the formation of a number of different compounds, such as dyestuffs, flavorings, fragrances, nucleating agents, polymer additives, and the like. The inventive method provides a very cost-effective and safe procedure for producing such substituted benzaldehydes at very high yields.
