ABSTRACT:
C.sub.4 olefins comprising cis- and trans-butane-2 and butene-1 may be oxidized to their corresponding mono- and diacetates in the presence of acetic acid and an olefin-activated palladium catalyst under mild conditions. With this catalyst, and depending in part upon the solvent employed, as well as other operating conditions, the formation of linear allylic 1-acetates over the corresponding branched compounds can be favored in order to increase the yield of the corresponding linear 1,4-diacetates. The latter, in turn, may then be converted, for example, to butanediol by known hydrogenation methods.
In a similar manner, isobutylene may be converted to a dialcohol.
