2,6-Dibromopyridine N-oxide and 4-nitro-2,6-dibromopyridine N-oxide were treated with tributyl(pyridin-2-yl)stannane under the conditions of the Stille coupling reaction. Derivatives of 2,2Ј-bipyridine 1-oxides as well as 2,2Ј:6Ј,2ЈЈ-terpyridine 1Ј-oxides were synthesised. Oxidation of 2,2Ј:6Ј,2ЈЈ-t
