The Noyori catalyst RuCl₂(R-Binap)(dmf)_n has been successfully encapsulated in C-FDU-12 by using the active chlorosilane Ph₂Cl₂Si as the silylating agent. ³¹P-NMR results show that there is no strong interaction between the molecular catalyst and the solid support, thus the encapsulated molecular catalyst could move freely in the nanoreactor during the catalytic process. The solid catalyst exhibits high activity and enantioselectivity for the asymmetric hydrogenation of a series of β-keto esters due to the preserved intrinsic properties of RuCl₂(R-Binap)(dmf)_n encapsulated in the nanoreactor. The solid catalyst could be recycled by simple filtration and be reused at least four times.
