The reaction of TiCl₄ with NH₃, CH₃OH and other Lewis bases in twin jet and merged jet deposition systems followed by trapping in argon matrices at 14 K has been examined. With twin jet deposition, formation of the initial intermediate, a 1:1 complex, was observed in each case. In a merged jet reactor, the reaction of TiCl₄ with CH₃OH proceeded very rapidly to a second intermediate, monomeric Cl₃TiOCH₃, which has been observed for the first time. Identification and characterization was carried out by extensive isotopic labeling, and comparison to density functional calculations. Increasing the temperature of the merged jet region to above 200\deg C led to the complete destruction of this species, and formation of additional products. Recent results on these and related systems will be reported.
