Al（I）化合物NacNacAl（1，NacNac = [ArNC（Me）CHC（Me）NAr]（-）和Ar = 2，6-（Pr 2C 6 H3）-C1）与H-X反应（X = H、Si、B、Al、C、N、P、O）H-2、硅烷、硼烷的a键（HBpin，pin =频哪酸盐），丙二烷（NacNacAlH（2）），膦（HPPh 2），胺，醇（（PrOH）-O-i），Cp*H（Cp* =五甲基环戊二烯）得到一系列四配位铝NacNacAlH（X）的氢化物衍生物，其在本文中通过光谱方法（NMR和IR）和X射线衍射表征。该方法允许合成铝的第一硼氢化物和新的硅氢化物和磷氢化物衍生物。在添加NacNacAlH（2）的情况下，反应是可逆的，证明了从物质NacNacAlH（X）还原消除的可能性。
The Al(I) compound NacNacAl (1, NacNac = [ArNC(Me)CHC(Me)NAr](-) and Ar = 2,6-(Pr2C6H3)-C-i) reacts with H-X (X = H, Si, B, Al, C, N, P, O) a bonds of H-2, silanes, borane (HBpin, pin = pinacolate), allane (NacNacAlH(2)), phosphine (HPPh2), amines, alcohol ((PrOH)-O-i), and Cp*H (Cp* = pentamethylcyclopentadiene) to give a series of hydride derivatives of the four-coordinate aluminum NacNacAlH(X), which are characterized herein by spectroscopic methods (NMR and IR) and X-ray diffraction. This method allows for the syntheses of the first boryl hydride of aluminum and novel silyl hydride and phosphido hydride derivatives. In the case of the addition of NacNacAlH(2), the reaction is reversible, proving the possibility of reductive elimination from the species NacNacAlH(X).
