Abstract

The new tin reagents, 2-(n-Bu3Sn)-6-{C (R) OCH2CH2O}-C5H3N,(R= H, Me), have been employed in Stille-type cross-coupling reactions with a range of oligopyridylbromides generating, following a facile deprotection step, a series of formyl-and acetyl-functionalised oligopyridines. Condensation reactions with 2, 6-diisopropylaniline has allowed access to families of novel sterically bulky multidentate N, N, N, N (tetradentate), N, N, N, N, N ( ...
