Carbonylation of butadiene in t-butyl alcohol catalyzed by a palladium complex gave t-butyl-3,8-nonadienoate (I). Further carbonylation of I in methanol with Co2(CO)8 afforded t-butylmethyl-3-decenedioate (II) as the main product. Hydrolysis and base-catalyzed isomerization of II produced E-2-decenedioic acid.
钯配合物催化丁二烯在叔丁醇中的羰基化,得到3,8-壬二烯酸叔丁酯(I)。I在甲醇中用Co 2(CO)8进一步羰基化,得到-3-癸烯二酸叔丁酯(II)作为主要产物。II的水解和碱催化的异构化产生了E -2-癸二酸。
