Tethering chiral Rh diene complexes inside mesoporous solids: experimental and theoretical study of substituent, pore and linker effects on asymmetric catalysis

Improved enantioselectivity in the 1,2-addition was observed for chiral Rh norbornadiene catalysts immobilized on ordered mesoporous silica with small pores. Confinement effects were rationalized by experimental and computational studies.
