The synthesis of three new sterically crowded titanium complexes which all possess an identical formamidinato ligand, two dimethylamido ligands and in addition, a 2‐aminopyridinato ligand that contains either an N‐methyl, an N‐phenyl, or an N‐cyclohexyl substituent is presented. All new complexes are easily accessible from a common titanium mono(formamidinate) precursor and correspondingly N‐substituted 2‐aminopyridines. Furthermore, the new complexes are used as catalysts for selected hydroamination and hydroaminoalkylation reactions and finally, the catalytic performance of the new catalysts is compared with the performance of the titanium mono(formamidinate) precursor.

新型钛配合物及其在加氢和加氢氨基烷基化反应中的应用

介绍了三种新的空间拥挤的钛配合物的合成，这些配合物均具有相同的甲酰胺基配体，两个二甲基酰胺基配体，此外还包含2-氨基吡啶并配体，其中包含N-甲基，N-苯基或N-环己基取代基。所有新的配合物都可以从常见的单（甲酰胺基）钛前驱体和相应的N-取代的2-氨基吡啶轻松获得。此外，将新的络合物用作选择的加氢胺化和氢氨基烷基化反应的催化剂，最后，将新催化剂的催化性能与单（甲酰胺基）钛前体的性能进行比较。
