文摘

A variety of 2,7-disubstituted derivatives of 1,8-naphthalenediol(2) of potential value asligands for the complexation of transition metals can be prepared from1,8-naphthalenediylbis(diethylcarbamate) (3) and1,8-bis(methoxymethoxy)naphthalene (9) by directedortho-metalation and subsequent functionalization. The reaction ofTiCl₄ with 1,8-naphthalenediol(2) in the presence of diisopropyl ketone produced an adductof a novel chloride-bridgeddimer of[1,8-naphthalenediolato(2^-)-O,O']dichlorotitanium(16; R = H). Its unusualstructure indicates that complexes derived from 1,8-naphthalenediolscan have features notnormally observed in complexes derived from simple phenols.
