Peng, Juan; Wang, Xuefeng; Zhang, Xiaoming; Bai, Shiyang; Zhao, Yaopeng; Li, Can; Yang, Qihua published an article in 2015, the title of the article was Asymmetric hydrogenation by RuCl2(R-Binap)(dmf)n encapsulated in silica-based nanoreactors.Electric Literature of 3976-69-0 And the article contains the following content:
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 mol. catalyst and the solid support, thus the encapsulated mol. catalyst could move freely in the nanoreactor during the catalytic process. The solid catalyst exhibits high activity and enantioselectivity for the asym. 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. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Electric Literature of 3976-69-0
