Titanium(IV) and zirconium(IV) derivatives of tetradentate schiff bases
1978
Titanium and zirconium isopropoxides react with the tetradentate Schiff bases, I)is-salicylaldehyde-o-phenylenediimine (SBH2 ) and bis-salicylaldehyde-p-phenylencdiimine (S′B′H2) in anhydrous benzene in 1: 1 and 1 :2 molar ratios to give almost quantitative yields of M(OPr-i)2 (SB) and M(OPr-i)2(SB)(SBH), where M = Ti or Zr and [SB]2 is the anion of the corresponding Schiff base, SBH2. The i.r. spectra of the completes have been recorded and tentative assignments for C=N and C-O stretching frequencies made.
