Figure 4. Substrate scope of the silylative kinetic resolution of racemic alcohol 2 catalysed by 1e.

The reactions were performed in the presence of 1 equiv of KF and 0.8 equiv of Amberlite CG 50 (CG 50). *Using catalyst 1c (X=Cl, 16.8% conv., s=20), catalyst 1d (X=Br, 36.7% conv., s=48), catalyst 1f (X=CF₃, 50.8% conv., s=50) and catalyst 1g (X=C₂F₅, 34.1% conv., s=30). ^†Using catalyst 1d (X=Br). e.r., enantiomeric ratio.
