Abstract:

Low temperature fluorine-19 NMR studies have been conducted on the following systems TiF4--TiBr4--Tetrahydropyran TiF4--TiI4--Donor Donor Tetrahydrofuran or 1,2-Dimethoxyethane TiF4--Methylal TiF4--H2O--1,2-Dimethoxyethane and, TiF4--TiCl4--H2O--Tetrahydrofuran. Systems involving methylal or TiI4 gave poorly resolved spectra which apparently resulted from rapid ligand exchange rates for these systems. All other systems produced well resolved spectra which could be interpreted on the bases of pseudo-octahedral structures formed by redistribution processes. Structural assignments as well as chemical shift and coupling constant data are presented for each observed complex. Water was found to be a strong donor capable of displacing either 1,2-dimethoxyethane or tetrahydrofuran.
