The nickel‐catalysed hydroalkoxylation of butadiene is promoted by a nickel(0)/dppb catalyst (dppb=1,4‐bis(diphenylphosphino)butane; see scheme). By following this new synthetic procedure, alkylbutenyl ethers are readily obtained from an alcohol and 1,3‐butadiene with exclusion of dimerisation and telomerisation products.
镍(0)/ dppb催化剂(dppb = 1,4-双(二苯基膦基)丁烷;参见方案)可促进丁二烯在镍催化下的加氢烷氧基化反应。通过遵循这种新的合成方法,可以从醇和1,3-丁二烯轻松获得烷基丁烯基醚,而不会出现二聚和端粒化产物。
