Following successful reductions of unfunctionalized heteroaromatic N-oxides by titanium(0), we applied this method to halogenated aromatic N-oxides to give the deoxygenated halogeno derivatives in 90-95% yield.

Suzuki–Miyaura cross-coupling of heteroaryl boronicesters with aryl or heteroaryl halides. The micellar catalysis enables this coupling reaction to run under mild conditions, which avoids the decomposition of heteroaryl boronate esters and allows for high chemoselectivity for cross-coupling reaction with 6-chloropridine-2-boronic ester. The micellar protocol expands the scope of the cross-coupling reaction
