Synthesis of sterically demanding phenoxide derivatives of Ti(IV) and Zr(IV), M( O-2,4,6-(t-Bu) 3C 6H 2) 2X 2 (X  NMe 2, M  Ti, Zr; X  Cl, M  Ti): x-ray crystal structure of Ti( O-2,4,6-(t-Bu) 3C 6H 2) 2(NMe 2) 2

Abstract

The interaction of M(NMe 2) 4 with excess 2,4,6-tri-t-butylphenol yields M{ O-2,4,6-(t-Bu) 3C 6H 2} 2(NMe 2) 2[M  Ti ( 1) (82%); M = Zr ( 2) (88%)]. Further reaction of 1 with neat Me 3SiCl yields M{ O-2,4,6-(t-Bu) 3C 6H 2} 2Cl 2 ( 3) (90% yield). The solid-state structure of 1 has been determined by a single-crystal X-ray diffraction study. The coordination geometry around Ti is a distorted tetrahedron.
