Reactions of [Ti(CO)(6)](2-) and chlorotriphenyl-methane or chlorotris
(4-methoxyphenyl)methane provide the first examples of trityltitanium
complexes. These have been shown by IR, NMR, and single-crystal X-ray
structural characterizations to have the molecular formula [Ti(CO)(4){
eta(5)-C(4-C6H4R)(3)}](-) (R = H, OCH3).
