The reactivity of bridgehead organo-lithium compounds with three nonenolisable ketones (hexamethylacetone, adamantanone and benzophenone) has been examined in various media. The condensations require use of mixed solvents (pentane-ether or pentane-THF), but secondary products are formed by solvent-attack. The alkylation of the bridgehead structure, by increasing the lipophilicity of the molecule, makes
已在各种介质中检查了桥头有机锂化合物与三种不可烯酮化的酮(六甲基丙酮,金刚烷酮和二苯甲酮)的反应性。缩合反应需要使用混合溶剂(戊烷-醚或戊烷-THF),但是副产物是通过溶剂攻击形成的。通过增加分子的亲脂性,桥头结构的烷基化使得可以将有机锂化合物溶解在烃中并在其中进行缩合。
