摘要:
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-4,4aEuro(3)-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 L-2(TiCl2)(2).
