Abstract

Reactions of 2-hydroxy-1-naphthaldehyde with 1,4-diaminobutane, 1,6-diaminohexane, 4,4′-methylenedianiline and its alkyl- and cycloalkyl-sybstituted derivatives, with 4,4′-sulfonyldianiline, 2,2′- and 4,4′-oxydianiline, 4,4′-(1,4-phenylenebisoxy)dianiline, 4,4′-[propane-2,2-diylbis(1,4-phenylenebisoxy)]dianiline, and p-terphenyl-4,4″-diamine afforded a series of the corresponding diimines that at treating with TiCl2(OPr-i)2 formed mono- and binuclear complexes of titanium(IV) dichloride with tetradentate ligands LTiCl2 and L2(TiCl2)2.
