The reaction between triisobutylaluminum and aliphatic 1-alkynes having alkyl groups of different structure on the 3-carbon atom has been investigated. At room temperature and in the absence of solvents, products which correspond to metallation, reduction and carbalumination processes, are isolated after hydrolysis. The extent of such reactions, and in particular the regiospecificity of the carbalumination
已经研究了三异丁基铝与在3-碳原子上具有不同结构的烷基的脂族1-炔之间的反应。在室温下,在没有溶剂的情况下,水解后会分离出对应于金属化,还原和碳酰化过程的产物。此类反应的程度,特别是碳氨化的区域特异性取决于所采用的实验条件以及与所用1-炔烃的结构相关的空间因素。基于这些结果以及当使用(+)(S -3,4-二甲基-1-戊炔)时反应的完全立体特异性,讨论了可能的机理。
