Synthesis and Molecular Structure of [Al(SiMe 3 ) 3 (DBU)] (DBU = 1,8-Diazabicyclo[5.4.0]undec-7-ene) Abstract. [Al(SiMe 3 ) 3 (OEt 2 )] reacts with DBU (DBU = 1,8diazabicyclo[5.4.0]undec-7-ene) at 0 °C yielding [Al(SiMe 3 ) 3 (DBU)] (1). 1 was characterised spectroscopically ( 1 H, 13 C, 29 Si, 27 Al NMR, IR, MS) and by X-ray structure determination [monoclinic, C2/c, a = 33.053(2), b = 9.307(1), c = 20.810(1) A Ê , b = 124.07(2)°, V = 5302.4(5) A Ê 3 , Z = 8, 218(2) K]. 1 does not react with [Cp 2 ZrCl 2 ] even in boiling toluene.
