Three salen aluminum bromide compounds salen(Bu)AlBr () (salen = ,'-ethylenebis(3,5-di--butylsalicylideneimine)), salpen(Bu)AlBr () (salpen = ,'-propylenebis(3,5-di--butylsalicylideneimine)), and salophen(Bu)AlBr () (salophen = ,'--phenylenenebis(3,5-di--butylsalicylideneimine) were evaluated for their potential use as dealkylation agents with a series of organophosphates. These reactions led to the aluminum phosphate compounds containing six-coordinate aluminum centers and hydrolytically stable P-O-C bonds: = [salen(Bu)AlOP(O)(OMe)], = [salen(Bu)AlOP(O)(OEt)], = [salen(Bu)AlOP(O)(OPh)], = [salophen(Bu)AlOP(O)(OMe)], = [salpen(Bu)AlOP(O)(OPr)], = (salen(Bu)AlO)PO, = (salpen(Bu)AlO)PO, = (salophen(Bu)AlO)PO. All the compounds were characterized by H, C, Al, and P NMR, IR, and mass spectrometry. Furthermore, compounds - were structurally characterized by single-crystal X-ray diffraction. The potential hydrolysis of these compounds was modeled with and demonstrated the unique stability of the final product and ease of isolation.
对三种水杨醛铝溴化合物水杨醛（丁基）铝溴（）（水杨醛 = ，'-亚乙基双（3,5 - 二叔丁基水杨基亚胺））、水杨醛（丙基）铝溴（）（水杨醛 = ，'-亚丙基双（3,5 - 二叔丁基水杨基亚胺））和水杨醛（苯基）铝溴（）（水杨醛 = ，' - 亚苯基双（3,5 - 二叔丁基水杨基亚胺））与一系列有机磷酸酯作为脱烷基化剂的潜在用途进行了评估。这些反应生成了含有六配位铝中心和水解稳定的P - O - C键的磷酸铝化合物： = [水杨醛（丁基）铝OP（O）（OMe）]， = [水杨醛（丁基）铝OP（O）（OEt）]， = [水杨醛（丁基）铝OP（O）（OPh）]， = [水杨醛（苯基）铝OP（O）（OMe）]， = [水杨醛（丙基）铝OP（O）（OPr）]， = （水杨醛（丁基）铝O）PO， = （水杨醛（丙基）铝O）PO， = （水杨醛（苯基）铝O）PO。所有化合物均通过H、C、Al和P核磁共振、红外光谱和质谱进行了表征。此外，化合物 - 通过单晶X射线衍射进行了结构表征。用 对这些化合物的潜在水解进行了模拟，证明了最终产物的独特稳定性和易于分离。
