4'-ALKOXY-2,2':6,2'-TERPYRIDINE DERIVATIVE AND METAL COMPLEX THEREOF

摘要

NEW MATERIAL:A compound expressed by formula I (R1 is alkyl substitutive by aryl, alkoxy, alkylthio, etc.); Py and Py' are 2-pyridyl). EXAMPLE:4'-Hexadecyloxy-2,2':6',2''-terpyridine. USE:Acting as a ligand for various metals and capable of providing metal complexes thereof with photocatalysis or physiological activity and coloring matters having high moist heat color fastness. PREPARATION:4'-Methansulfonyl-2,2':6',2''-terpyridine expressed by formula II is reacted with a compound expressed by the formula R1-OH in the presence of a base (e.g., NaH) in a solvent, such as dimethylformamide, at 30-200 deg.C to afford the compound expressed by formula I. A 4'-alkoxy-2,2':6',2''-terpyridine can be reacted with a metal salt to readily provide the corresponding metal complex.
