Abstract

Chloride phenoxides of type MCl4-n(OAr')n (where M = Ti or Zr; n = 1, 2 or 3) have been prepared by the interaction of the metal chlorides with 2,4,6-trimethylphenol (Ar'OH). The mixed chloride phenoxides showed considerable reactivity as Lewis acids towards bases, resulting in addition complexes of general formula MCl4-n(OAr')nL2 (where L = primary or tertiary aromatic amines, or oxygen- or phosphorus-containing bases). These complexes have been characterized by IR and the 1H NMR studies, conductivity measurements, molecular weight measurements (in the case of soluble products), thermogravimetric and mass spectral studies.
