3,5-Di-(pyridin-2-yl)-[1,2,4]-triazines 3 are converted to 4-tributylstannyl-2,6-oligopyridines 5 regioselectively via [4+2] cycloadditions with ethynyltributyltin. Bromination of the tin compounds 5 leads to 4-bromo-2,6-oligopyridines 7. Cross-coupling reactions of compounds 5 and 7 under Stille conditions yield branched oligopyridines 8 containing 8 to 14 pyridine units. (C) 1999 Published by Elsevier Science Ltd.
