In the oligomerization of butadiene with the catalyst composed of iron(III) acetylacetonate and triethylaluminum, the degree of digomerization and the structures of the oligomers were strongly affected by the addition of an electron donor as a catalyst component. When triphenylphosphine was added, linear dimers composed of 3-methylhepta-1, 4, 6-triene and n-octa-1, 3, 6-triene were formed, while the
在丁二烯与乙酰丙酮铁(III)和三乙基铝组成的催化剂的低聚反应中,低聚度和低聚物的结构受电子给体作为催化剂组分的加入的强烈影响。当加入三苯基膦时,形成由 3-甲基七-1, 4, 6-三烯和正辛基-1, 3, 6-三烯组成的线性二聚体,而加入 2, 2'-联吡啶产生由以下组成的环状二聚体cycloocta-1, 5-diene 和 4-vinylcyclohex-1-ene。除上述供体外,亚磷酸三苯酯、亚磷酸三(邻甲苯基)、亚磷酸三(对甲苯基)、三氯化磷、三乙胺和吡啶作为单齿,邻菲咯啉、2(2'-吡啶基)咪唑啉和肟作为双齿配体,并研究了这些供体对反应的影响。
