  Use a solvent blend that contains 1-methoxy-2,7-octadiene and an alkanols rather than the alkanols by itself to prepare a catalyst precursor suitable for use in butadiene telomerization.

  使用含有 1-甲氧基-2,7-辛二烯和烷醇而非烷醇本身的混合溶剂来制备适用于丁二烯端聚合反应的催化剂前体。

  Catalyst compositions are prepared by contacting a palladium source and 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane and a methoxyocta-diene compound, in a primary aliphatic alcohol, under suitable conditions including a ratio of equivalents of palladium to equivalents of 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaadamantane ranging from greater than 1:1 to 1:1.3. The result is a complex of palladium, a 1,3,5,7-tetramethyl-6-(2,4-dimethoxyphenyl)-2,4,8-trioxa-6-phosphaada-mantane ligand, and a ligand selected from a methoxyoctadiene ligand, an octadienyl ligand, or a protonated octadienyl. Such complexes may, in solution, exhibit surprising solubility and storage stability and are useful in the telomerization of butadiene, which is a step in the production of 1-octene.

  催化剂组合物的制备方法是将钯源和 1,3,5,7-四甲基-6-(2,4-二甲氧基苯基)-2,4,8-三氧杂-6-磷杂金刚烷以及甲氧基辛二烯化合物在一级脂肪醇中接触、在适当的条件下，包括钯的当量与 1，3，5，7-四甲基-6-(2，4-二甲氧基苯基)-2，4，8-三氧杂-6-磷杂金刚烷的当量之比大于 1：1 至 1:1。3.结果是一种钯、1,3,5,7-四甲基-6-(2,4-二甲氧基苯基)-2,4,8-三氧杂-6-磷杂金刚烷配体和选自甲氧基辛二烯配体、辛二烯配体或质子化辛二烯配体的络合物。这种复合物在溶液中可以表现出惊人的溶解性和贮存稳定性，可用于丁二烯的端聚反应，这是生产 1-辛烯的一个步骤。
