Lithium TMP-aluminate "(i)Bu(3)Al(TMP)Li" undergoes dismutation in THF solution to precipitate the tetraalkylaluminate [{Li.(THF)(4)}(+){Al((i)Bu)(4)}(-)], but reacts kinetically as a TMP base towards N,N-diisopropylbenzamide to afford the crystalline ortho-aluminated species [(THF)(3).Li{O([=C)N((i)Pr)(2)(C(6)H(4))}Al((i)Bu)(3)] and TMPH.
锂三甲基戊基铝酸盐“(i)Bu(3)Al(TMP)Li”在四氢呋喃溶液中发生歧化反应，沉淀出四烷基铝酸盐[{Li.(THF)(4)}(+){Al((i)Bu)(4)}(-)]，但在动力学上作为一种三甲基戊基碱与N,N -二异丙基苯甲酰胺反应，生成结晶性的邻位铝化产物[(THF)(3).Li{O([=C)N((i)Pr)(2)(C(6)H(4))}Al((i)Bu)(3)]和三甲基戊基氢化物。
