Czakler M, Puchberger M, Artner C, Schubert U - Monatsh. Chem. (2014)

Bottom Line: The coordination polymer [Ti(OiPr)3(OOCCH2CH2CH2C3N2H3)] n was prepared from 4-(imidazol-1-yl)butyric acid and titanium isopropoxide.The structure of the compound is remarkable, as the carboxylate group is coordinated in a chelating manner and no dimerization of the Ti(OiPr)3 groups through OR bridges was observed.

Fig4: 1H/15N HMBC NMR spectrum of the complex 1 in CD2Cl2

Mentions: The solution 1H NMR spectrum of 1 shows one doublet at 1.22 ppm for the terminal CH3 of the OiPr ligands. The signals of the imidazolyl group appear at 6.73, 7.19, and 7.59 ppm. To verify the coordination behavior of the imidazolyl group in solution, 2D correlation spectra (1H/15N HMBC) of L–H and the complex were recorded. The spectrum of the complex (Fig. 4) shows correlations at 152 and 224 ppm, while the spectrum of the free ligand shows correlations at 153 and 239 ppm. The shift difference of 15 ppm for one of the two nitrogen atoms is an indication that coordination is retained in solution.Fig. 4
