Abstract
A novel four step process for the preparation of symmetric terpyridine s is presented. The title compound, 2,2':6',2 ''-terpyridine (1a) and a substituted derivative, 5,5 ''-dimethyl-2,2':6',2 ''-terpyridine (1b ) are prepared. Both 1a and 1b share a common precursor, 2,6-diacetylp yridine (2) and are prepared in overall yields of 73 and 93% respectiv ely. The purities of the crude terpyridine products are in the 90-95% range. (C) 1998 Elsevier Science Ltd. All rights reserved.
