Abstract
The reaction between titanium isopropoxide and acetyl bromide has been studied and the following compounds, TiBr(OPri)3, TiBr2(OPri)2 · 0.5 CH3COOPri, TiBr3(OPri) · CH3COOPri and TiBr4 · CH3COOPri have been isolated. The tri- and tetra-bromide derivatives sublime with their ester of addition. The great ease with which these compounds exchange their radicals has been demonstrated by the reaction between dibromide and excess tetra-isopropoxide, whereby the monobromide crystallized out in quantitative yield. The monobromides and dibromides react with butanols or butyl acetates, to give products in which the alkoxy groups have been replaced. A number of normal and secondary butoxide derivatives have been isolated, but side-reactions occur in the case of tertiary butoxides, yielding decomposition products. It was shown that the reaction between TiBr4 · CH3COOPri and excess isopropanol produces TiBr2(OPri)2.
