Tetrahydroindenyltitanium compounds

These results indicated that highly active titanium compounds exhibit one cylopentadienyl ligand with electron-donative substituents, and bulky substituents reduce the catalytic activities. From this point of view, 1,2,3-tri-methyl-tetrahydroindenyltitanium compounds were examined, resulting in high catalytic activities (Table 2.6). 

The effect of methyl groups as substituents in tetrahydroindenyltitanium compounds is shown in Figure 2.3. The catalytic activities and the stabilities of the compounds are changed by the substituents.
