Trityltitanium Complexes. X-ray Structural Characterization of [Ti(CO)4{η5-C(4-C6H4R)3}]- (R = H, OCH3)1

Reactions of [Ti(CO) 6 ] 2 - and chlorotriphenylmethane 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 {η 5 -C(4-C 6 H 4 R) 3 }] - (R = H, OCH 3 ).
