Abstract:
We theoretically demonstrate the possibility of dynamically controlling catalysis by nanomechanical means. This novel methodology is based on switching the configuration (activity) of catalysts docked on nanoscale surfaces that are reversibly deformed. We test the approach by molecular dynamics simulations of an organic chiral catalyst that is docked by van der Waals coupling on twisted carbon nanotubes. Our results show that its catalytic activity is sharply correlated with the direction and amount of the nanotube twist. We also observe a small selectivity in docking of chiral molecules on straight helical nanotubes.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
