Summary: Beta-cyclodextrin-based adsorbents show unique characteristics and can form host-guest complexes with various organic compounds. The adsorption capacity has been improved through different preparation strategies and crosslinking agents. The adsorbents can be classified based on preparation methods, and composite/nanocomposite beta-cyclodextrin-based adsorbents exhibit high adsorption capacity, especially for dyes. The hydrogel of beta-cyclodextrin/chitosan functionalized graphene oxide and beta-cyclodextrin/chitosan modified with iron(II, III) oxide nanoparticles demonstrate outstanding adsorption capacity.

Summary: The study reported the asymmetric synthesis of chiral benzo-ring containing compounds through enantioselective intramolecular arylation of unbiased methylene C(sp(3))-H bonds. The key lies in choosing a suitable non-C-2-symmetric chiral phosphoric acid (CPA) ligand for high reactivity and enantioselectivity. The slight decrease in enantioselectivity towards the end of the reaction was attributed to the hydrolysis of CPA ligands into BINOL.

Summary: This article describes a catalytic 1,2-oxyhalogenation method that converts non-conjugated internal alkynes into tetrasubstituted alkenes with high selectivity. The selectivity depends on the formation of a six-membered palladacycle intermediate in the oxypalladation step and the identity of the halide anion.

Summary: This study presents a palladium-catalyzed asymmetric functionalization of unbiased methylene C(sp(3))-H bonds, using a specific directing group and chiral ligand to achieve high enantioselectivity in arylation reactions. The combination of aryl iodides with the chiral ligand was found to be beneficial for achieving high enantiocontrol. The PIP directing group could be easily removed without compromising enantiopurity.
