variations of the synthetically useful aluminate [L x Li(TMP)((i)Bu)Al((i)Bu)2], where L is TMPH, Et3N or PhC(=O)N(i)Pr2, are reported, together with the reaction of the benzamide complex with 1,4-dioxane, which surprisingly leads to fragmentation of the cyclic ether and capture of its alkoxy vinyl ether residue within a novel dilithium dialuminium hexaalkyl aggregate.
合成有用的铝酸盐的三个Lewis碱变体[L x Li(TMP)((i)Bu)Al((i)Bu)2],其中L是TMPH,Et3N或PhC(= O)N(i)Pr2,据报道,苯甲酰胺配合物与1,4-二恶烷的反应令人惊讶地导致环状醚的断裂并在新型二锂二铝六烷基二锂聚集体中捕获其烷氧基乙烯基醚残基。
