A NiCl(2)-6H(2)O/Zn reagent with a 2-aryliminomethylpyridine ligand catalyzed cyclization/polymerization of 1,6-diynes to yield mainly the corresponding poly(1,3-butadienylene) compounds, whereas NiBr(2)-3H(2)O/Zn with the use of 3-(2-(2-methoxyethoxy)-ethyl)-1-methyl-1H-imidazol-3-ium bromide as a ligand converted 1,6-diynes to the corresponding annulated 1,3,5,7-cyclooctatetraenes in a biphasic solvent
具有2-芳基氨基甲基吡啶配体的NiCl(2)-6H(2)O / Zn试剂催化1,6-二炔的环化/聚合反应,主要产生相应的聚(1,3-丁二烯)化合物,而NiBr(2)使用3-(2-(2-甲氧基乙氧基)-乙基)-1-甲基-1H-咪唑-3-溴化铵作为配体的-3H(2)O / Zn将1,6-二炔转化为相应的在由甲苯和离子液体组成的双相溶剂体系中环化1,3,5,7-环辛酸酯。
