five- and six-coordinate titanium and zirconium dialkyl complexes that contain the [(i-PrN-o-C6H4)2O]2- ([i-PrNON]2-) ligand have been prepared, among them [i-PrNON]Ti(CH2CHMe2)2, [i-PrNON]Ti(CH2CMe3)2, [i-PrNON]Zr(CH2CH3)2, and [i-PrNON]Zr(CH2CHMe2)2. These species serve as sources of complexes such as [i-PrNON]Ti(PMe3)2}2(μ-N2), [i-PrNON]Ti(CHCMe3)(PMe3)2, [i-PrNON]Zr(CH2CHMe2)2(PMe3), and [i-PrNON]Zr(H2CCMe2)(PMe3)2
已经制备了多种含有[(i-PrN-o-C6H4)2O]2-([i-PrNON]2-)配体的五配位和六配位钛和锆二烷基配合物,其中[i- PrNON]Ti(CH2CHMe2)2、[i-PrNON]Ti(CH2CMe3)2、[i-PrNON]Zr(CH2CH3)2 和 [i-PrNON]Zr(CH2CHMe2)2。这些物质作为复合物的来源,例如 [i-PrNON]Ti(PMe3)2}2(μ-N2)、[i-PrNON]Ti(CHCMe3)(PMe3)2、[i-PrNON]Zr(CH2CHMe2) )2(PMe3) 和 [i-PrNON]Zr(H2CCMe2)(PMe3)2。[i-PrNON]Ti(CH2CMe3)2 和 Me2PCH2CH2PMe2 在不存在二氮的情况下反应生成 (i-PrNC6H4)(i-PrNC6H4O)Ti(dmpe),一种假八面体物质,其中一个芳基-氧键已被裂解。在[i
