Tetra-8-quinolinolatotitanium, di-8-quinolinolatodisalicylaldehydatotitanium, and tetrasalicylaldehydatotitanium

Abstract

Tetra-8-quinolinolatotitanium (Ti ox₄) has been prepared by the reaction of dichlorodi-8-quinolinolatotitanium with 8-quinolinol in the presence of triethylamine. Tetrasalicylaldehydatotitanium (Ti sal₄) and di-8-quinolinolatodisalicylaldehydatotitanium (Ti ox₂ sal₂) have been prepared by analogous reactions. Conductance and spectroscopic evidence indicates that titanium is eight-co-ordinate in Ti ox₄ but probably six-co-ordinate in Ti sal₄ and Ti ox₂ sal₂. Attempts to prepare tetra-acetylacetonatotitanium by the analogous reaction gave Ti acac₃.
