It has been found that palladium-phosphine complexes coordinated by dienophile and tetrakis-(triphenylphosphine) palladium catalyzed the linear dimerization of butadiene. The dimerization of butadiene with bis(triphenylphosphine)(maleic anhydride)palladium in aprotic solvents, such as benzene, tetrahydrofuran, and acetone, gave octatriene-1,3,7 selectively in good yields. In such alcohols as methanol
已经发现由亲二烯体和四-(三苯基膦)钯配位的钯-膦配合物催化丁二烯的线性二聚化。丁二烯与双(三苯基膦)(马来酸酐)钯在非质子溶剂(如苯、四氢呋喃和丙酮)中的二聚反应以良好的收率选择性地得到辛三烯-1,3,7。在甲醇、乙醇和异丙醇等醇中,丁二烯转化为 1-烷氧基辛二烯-2,7 和/或辛三烯-1,3,7,这取决于所用醇的性质。在仲胺(如吗啉、哌啶和二异丙胺)中的二聚反应得到 R2N(C8H13) 型的丁二烯二聚-胺加合物,而在伯胺(如苯胺和正丁胺)中的二聚反应得到 RNH(C8H13) 型的混合物) 和 RN(C8H13)2。
