Cross-linked reverse micelles with embedded water pools: A novel catalytic system based on amphiphilic block copolymers

Based on the idea of structural design, a novel catalytic system was developed from a block copolymer for the oxidation reaction of 2,3,6-trimethylphenol (TMP). The block copolymer, poly(4-vinylpyridine)-block- poly(ethylene glycol)-block-poly(4-vinylpyridine) (P4VP-PEG-P4VP), was synthesized via anionic polymerization. After self-assembly in water-1-hexanol solution and shell cross linking, the block copolymer formed the shell cross-linked reverse micelles (SCRMs). The CuCl2 complexed SCRMs were used in the catalytic oxidation reaction of TMP. Through coordinating with metal ions, regulating the distribution of metal catalytic active centers, and with the cocatalysis effect of the immobilized water droplets, this polymer-supported catalyst system demonstrated an efficient catalytic activity and recoverability. This work not only provides a promising catalyst based on mesoscale structure design using block copolymers but is also an example for deeper understanding on the structure effect in catalysis. the Partner Organisations 2014.

Aromatic substitution in ball mills: Formation of aryl chlorides and bromides using potassium peroxomonosulfate and NaX

Aryl chlorides and bromides are formed from arenes in a ball mill using KHSO5 and NaX (X = Cl, Br) as oxidant and halogen source, respectively. Investigation of the reaction parameters identified operating frequency, milling time, and the number of milling balls as the main influencing variables, as these determine the amount of energy provided to the reaction system. Assessment of liquid-assisted grinding conditions revealed, that the addition of solvents has no advantageous effect in this special case. Preferably activated arenes are halogenated, whereby bromination afforded higher product yields than chlorination. Most often reactions are regio- and chemoselective, since p-substitution was preferred and concurring side-chain oxidation of alkylated arenes by KHSO5 was not observed.

Synthesis of Alkyl Substituted p-Benzoquinones from the Corresponding Phenols Using Molecular Oxygen Catalyzed by Copper(II) Chloride-Amine Hydrochloride Systems

2,4,6-Trimethylphenol was effectively oxidized to trimethyl-p-benzoquinone with molecular oxygen in the presense of a catalytic amount of copper(II) chloride-amines in alcohol at ambient temperature.Various amines could be used as a co-catalyst in the presence of acids, and especially hydroxylamine hydrochloride and acetone oxime coupled with hydrochloric acid showed high activity. 2,6-Dimethyl-p-benzoquinone was also obtained from 2,6-dimethylphenol in good yield in this catalytic oxidation system.
