 (ăr′əl, âr′-)
A compound containing benzene or another aromatic hydrocarbon, or a univalent group derived from such a compound by removal of a hydrogen atom attached to the aromatic ring.


1. (Elements & Compounds) (modifier) chem of, consisting of, or containing an aromatic group: aryl group or radical.
2. (Elements & Compounds) an organometallic compound in which a metal atom is bound to an aryl group
[C20: from ar(omatic) + -yl]


(ˈær ɪl)

an organic group derived from an aromatic compound by removing a hydrogen atom, as phenyl from benzene.

They cover asymmetric C-H bond insertion reactions, symmetric cross-dehydrogenative coupling reactions, asymmetric oxidative biaryl coupling reactions, asymmetric [1,5]-hydride transfer reactions, asymmetric functionalization of C-H bonds via a transient carbon-metal species, asymmetric Friedel-Crafts alkylation reactions, N-heterocyclic carbene-catalyzed asymmetric functionalization of aldehyde C-H bonds, asymmetric hydroacylation reactions, and asymmetric hydrovinylation reactions.
Biaryl structures are extensively found in many of the natural products including terpenes, alkaloids, flavonoids, lignan, and tannins etc [1, 2].
Biaryl compounds play an important role in medicinal chemistry and drug discovery.
Thus, we will develop catalytic cross-coupling processes proceeding via (1) gold(I) mediated C-H activation of electron poor arenes, (2) oxidation of the catalyst to gold(III) followed by gold(III) mediated C-H activation of electron rich arenes, and (3) C-C bond formation furnishing biaryl compounds.
