Catalytic intermolecular cycloalumination of cyclic 1,2-dienes with terminal allenes or disubstituted acetylenes mediated by EtAlCl2 in the presence of complexes based on transition metals was accomplished. The yield of unsaturated bicyclic aluminacarbocycles was up to 85%.
在基于过渡金属的配合物存在下,由 EtAlCl2 介导的环状 1,2-二烯与末端丙二烯或二取代乙炔的催化分子间环铝化反应得以完成。不饱和双环铝碳环的产率高达85%。
