such, the correction parameter g is still calculated as the rate of the heterochiral catalytic complex divided by the rate of the homochiral catalytic complex. However, since the heterochiral complexes lead to enantiomerically enriched product, the overall equation for calculating the eeproduct becomes more difficult. In Figure 8., the mathematical formula for calculating enantioselectivity is shown. Figure 8: The mathematical formula describing an ML3 system. The eeproduct is calculated by multiplying the eemax by the correction factor developed by Kagan and co-workers. Interpretation of the ML3 Model In general, interpreting the correction parameter values of g to predict positive and negative non-linear effects is considerably more difficult. In the case where the heterochiral complexes MLRLRLS and MLSLSLR are less reactive than the homochiral complexes MLSLSLS and MLRLRLR, a kinetic behavior similar to the ML2 model is observed (Figure 9). However, a substantially different behavior is observed in the case where the heterochiral complexes are more reactive than the homochiral complexes. Reservoir Effect General Description Often described adjacent or in collaboration with the ML2 model, the reservoir effect describes the scenario in which part of the chiral ligand is allocated to a pool of inactive heterochiral catalytic complexes outside the catalytic cycle. A pool of unreactive heterochiral catalysts, described with an eepool, develops an equilibrium with the catalytically active homochiral complexes, described with an eeeffective. Depending on the concentration of the inactive pool of catalysts, one can calculate the enantiopurity of the active catalyst complexes. The general result of the reservoir effect is an asymmetric amplification, also known as a (+)-NLE. Origin of the Reservoir Effect The pool of unreactive catalytic complexes, as described in the reservoir effect, can be the result of several factors. One of these could potentially be an aggregation effect amongst the heterochiral catalytic complexes that takes place prior to the steady state equilibrium. Early Examples of the Non-Linear Effect Sharpless Epoxidation of Geraniol In 1986, Kagan and co-workers were able to demonstrate NLE with the Sharpless epoxidation of (E)-Geraniol (Figure 11). Under Sharpless oxidizing conditions with Ti(O-i-Pr)4/(+)-DET/t-BuOOH, Kagan and coworkers were able to demonstrate that there was a non-linear correlation between the eeproduct and the ee of the chiral catalyst, diethyl tartrate (DET). As one can see from Figure 11, a greater eeproduct than expected was observed. According to the ML2 model, Kagan and coworkers were able to conclude that a less reactive heterochiral DET complex
