C4 olefins comprising cis- and trans-butene-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 favoured 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.
由顺式和反式丁烯-2 和丁烯-1 组成的 C4 烯烃可在乙酸和烯烃活化钯催化剂存在下,在温和条件下氧化成相应的单乙酸酯和二乙酸酯。 使用这种催化剂,并部分取决于所使用的溶剂以及其他操作条件,可以更有利于形成线性烯丙基 1-乙酸酯,而不是相应的支链化合物,以增加相应的线性 1,4-二乙酸酯的产量。 然后,后者可以通过已知的氢化方法转化为丁二醇等。 异丁烯也可以通过类似的方法转化为二元醇。
