The selective and predictable C-H functionalization of arenes is a valuable method for the synthesis modification organic molecules in which regioisomer formation often controlled by electronic factors or presence coordinating groups. On other hand, iridium-catalyzed borylation can achieve unique steric-controlled regioselectivity. In this account, we describe our recent studies on arenes: deve...

friedel–crafts synthesis of triarylmethanes over 3-methyl-1-sulfonicacid imidazolium tetrachloroaluminate under green conditions:in this work, friedel–crafts (fc) alkylation of various arenes with aromatic aldehydes catalyzed by 3-methyl-1-sulfonic acid imidazoliumtetrachloroaluminate {[msim]alcl4}, as a green catalyst, to prepare triarylmethanes (tams) has been carried out. some aromatic aldeh...

The formation of a pH-responsive fluorescent [5]pseudorotaxane by self-assembly of cationic water-soluble pillar[5]arenes and a tetraphenylethene derivative was reported.

Two lower rim halogenated pyrogallol[4]arenes have been synthesised and structurally characterised as either bi-layer or hexameric nano-capsule motifs depending upon chain length and functionalisation.

Benzoin alkyl ethers encapsulated in a cisoid conformation within water-soluble p-sulfonatocalix[8]arenes preferentially yield the Norrish Type II reaction product deoxybenzoin.

We report on hybrids of water-soluble calix[8]arenes and single-walled carbon nanotubes (SWCNTs); the hybrids formed supramolecular SWCNTs network polymer by adding guest dimer.

The pyridone fragment in the ligand [2, 2’-bipyridin]-6(1H)-one (bipy-6-OH) enables oxidative Heck reaction of simple arenes with oxygen as sole oxidant and no redox mediator. Arenes either electron-donating or electron-withdrawing groups can be functionalized this way. Experimental data on toluene model arene shows that C−H activation step is turnover limiting structure crucial to facilitate r...

Resorcin[4]arenes in an apolar solvent containing alcohols exist in three forms of self-assembled aggregates which have been characterised by the technique of diffusion NMR spectroscopy.

Bromomethyl arenes used as polyfunctional core of dendrimers were derivatized with diethanolamine branches. The obtained compounds containing 4 or 6 hydroxyl terminal surface groups are highly water-soluble.
