摘要
The synthesis of 2,2 ' -bipyridine, 1,10-phenantroline and 2,2 ' :6 ' ,2 " -terpyridine substituted by an ethylester function is described. The 5- and 6-methyl-2,2 ' -bipyridines bearing an ethylester group on the 6 ' position as well as the ethyl 6,6 " -dimethyl-2,2 ' :6 ' ,2 " -terpyridine-4 ' -carboxylate moiety were synthesized via a Stille cross-coupling reaction, starting from bromo-picoline building blocks. A radical bromination of the methyl-oligopyridine gave selectively the corresponding benzylic bromide derivatives in fair yield. (C) 2001 Elsevier Science Ltd. All rights reserved.
