A fluorine-19 nuclear magnetic resonance spectral study of some titanium tetrafluoride diadducts

Abstract

An ¹⁹F n.m.r. study of some diadducts of titanium tetrafluoride with some 4-substituted pyidine 1-oxides, 4-sub-stituted quinoline 1-oxides, and 6-substituted quinoline 1-oxides is reported. Correlations between ¹⁹F chemical shift and substituent constant values are discussed. Two geometrical isomers are observed for some of the complexes. The data are interpreted in terms of fluorine to metal π-bonding.
