Asymmetric nucleophilic addition
The aim is to understand and control chirality transfer, catalytic activity and mechanism of chiral diene-metal complexes covalently tethered inside a mesoporous material by using the asymmetric Rh-catalyzed 1,4-addition of boronic acids to enones as a benchmark system. The confinement effects resulting from a) the steric confinement of the catalyst and substrate in a pore of certain size and geometry, b) the polarity gradient between the inner pore surface and the catalyst in the centre and c) solvent interactions with inner pore surface and the ligand sphere will be examined by various experimental and theoretical methods.
