《Hypercrosslinking chiral Bronsted acids into porous organic polymers for efficient heterogeneous asymmetric organosynthesis》 was published in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2021. These research results belong to Zhang, Yuwei; Zhang, Zhenwei; Ma, Si; Jia, Ji; Xia, Hong; Liu, Xiaoming. SDS of cas: 189518-78-3 The article mentions the following:
A construction strategy for directly immobilizing the axially chiral phosphoric acid into hypercrosslinked polymers by a one-pot Friedel-Crafts alkylation reaction was developed. The obtained chiral polymers have high porosity, excellent stability and tailorable catalytic centers, and display excellent activity, enantioselectivity and recyclability for asym. transfer hydrogenation. The experimental process involved the reaction of (R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3SDS of cas: 189518-78-3)
(R)-3,3′-Diiodo-2,2′-bis(methoxymethoxy)-1,1′-binaphthalene(cas: 189518-78-3) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. SDS of cas: 189518-78-3 Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.
