Abstract

Figure 1. Reaction sequence for the formation of 4'4nyl-2, 2': 6', 2''-terpyridine. drolyzed with 20% aqueous potassium hydroxide in dimethoxyethane with a catalytic amount of dibenzo- 18-crown-6. An alternative procedure (80% yield) involved the reaction of 1, 5-di-2- pyridylpentane-l, 3, 5trione (4) with hot ammonium acetate, the trione itself being obtained (80% yield) from the Claisen condensation of ethyl 2-pyridinecarboxylate and acetone." ...
