iPr, R2 = H; 2, R1 = Me, R2 = H; 3, R1 = Me, R2 = Me) with MMe4 (M = Hf, Zr) afforded metal complexes 1-HfMe3, 2-HfMe3, 3-HfMe3, and 1-ZrMe3 in high yields. Treatment of ligand 1 with Ti(NMe2)4 resulted in the formation of 1-Ti(NMe2)3, which reacted with SiMe2Cl2 to form 1-TiCl3. 1-TiMe3 was obtained by alkylation of 1-TiCl3 with MeMgBr. All metal complexes were characterized by 1H and 13C NMR spectroscopy
具有高活性和高热稳定性的均相金属催化剂的开发对于在溶液相烯烃聚合工艺中合成聚烯烃弹性体(POE)至关重要。在这方面的贡献,8-(2,6-(R的化学计量反应1)2 -4-R 2 -anilide)-5,6,7,8--trihydroquinoline(1 - 3 ; 1,R 1 =我镨,R 2 = H; 2,R 1 = Me,R 2 = H; 3,R 1 = Me,R 2 = Me)与MMe 4(M = Hf,Zr)提供金属配合物1-HfMe 3,2-HfMe 3,3-HfMe 3,和1-ZrMe 3以高产率。用Ti(NMe 2)4处理配体1导致形成1-Ti(NMe 2)3,其与SiMe 2 Cl 2反应形成1-TiCl 3。1-TiMe 3通过用MeMgBr烷基化1-TiCl 3获得。所有金属配合物的特征是1 H和13C NMR光谱,和配合物的分子结构1-HfMe 3,2-HfMe 3,1-
