low-valent [Cp*Al]4 and trialkylsilyl azides RR‘2SiN3 proceed with N2 elimination and subsequent formation of iminoalanes [Cp*AlNSiRR‘2]x (R, R‘ = Et 1, i-Pr 2, t-Bu 3; R = t-Bu R‘ = Me 4), which further react with an equimolar amount of 4-(dimethylamino)pyridine (dmap) with formation of dmap-stabilized iminoalanes of the general type [dmap-Al(Cp*)NSiRR‘2]2 (R, R‘ = Et 5, i-Pr 6; R = t-Bu R‘ = Me 7).

低原子价之间的反应的[Cp *的Al] 4和三烷基甲硅烷基叠氮化物RR ' 2的SiN 3继续用N 2去除和随后形成的iminoalanes的[Cp * AlNSiRR' 2 ] X(R,R” =的Et 1,我-Pr 2,t -Bu 3; R = t -Bu R'= Me 4),进一步与等摩尔量的4-(二甲氨基)吡啶(dmap)反应,形成一般类型的dmap稳定的亚氨基丙氨酸[dmap-Al (CP *)NSiRR ' 2 ] 2(R,R'=的Et 5,我-Pr6;R = t -Bu R'= Me 7)。观察到的[Cp * AlNSi(无反应吨-Bu)3 ] 2,3。相比之下中,Cp * Al和RR” 2的SiN 3在升高的温度下与邻-H的C-H活化在DMAP的存在下反应的DMAP和地层的类型的二氢蒽型化合物[ ø -Al(CP *) N(H)SIRR ' 2 -dmap] 2(R,R'=的Et
