Die Cooligomerisierung von butadien mit α-hydroxycarbonsäureestern

Abstract Glycolic acid butyl ester as well as lactic acid ethyl ester react with butadiene in the presence of palladium(II) acetylacetonate and triphenylphosphine as catalyst. The main product is the 2-trans, 7-octadienyl ether of the hydroxy acid ester, which is formed in yields from 65 to 80% at room temperature.
