Ruthenium/base-catalyzed ortho-selective C–H arylation of acylarenes with halogenated arylboronates†
Abstract
Ruthenium-catalyzed ortho-selective C–H arylation of acylarenes with halogenated aryl-boronates was promoted by the catalytic amount of bases and provided desired halogenated biaryls in excellent yields under 0.2–1 mol% ruthenium catalyst loading.
