- W3000320996 abstract "为了研究铝(Ⅲ)与生命体中重要的有机分子a-酮戊二酸的作用机制,我们采用了电位滴定、核磁共振、拉曼光谱和分子力学计算对酸性溶液中的反应体系的配位作用和互变异构进行了分析,并采用电喷雾质谱以及固体和溶液核磁共振谱表征了浓溶液反应体系中的沉淀,来说明铝(Ⅲ)对a-酮戊二酸的催化脱羧反应过程.得到如下实验结论:(1)配位作用:铝(Ⅲ)与a-酮戊二酸在酸性溶液中配位形成11[AlLH2+,AlL+,AlLH-1]和1:2[AlLα-,Al2H-23-]的单核形态以及2:1[Al2L4+]的双核形态.(2)互变异构:在酸性溶液中Al3+通过配位作用促进a-酮戊二酸烯醇化,生成易于脱羧的β、γ-不饱和酸的结构.(3)催化脱羧:由于铝(Ⅲ)的电子沉降作用,使β、γ-不饱和酸更易脱羧,如果是1:2的形态,则脱羧生成沉淀." @default.
