We also varied the titanium chloride to isopropoxide ratio from 3:1 to 1:3 while keeping the overall titanium concentration 0.2 mol/L (Figure ). After ligand scrambling, this respectively yields TiCl 3 (O i Pr), TiCl 2 (O i Pr) 2 and TiCl(O i Pr) 3 as reagents. The higher chloride content not only accelerates the reaction but again changes the shape of the decomposition trace. For TiCl 3 (O i Pr), the decomposition is described well by a single exponential (first order kinetics), Figure . For TiCl 2 (O i Pr) 2 and TiCl(O i Pr) 3 , a linear fit is most adequate.
