Reactivity of tervalent titanium compounds ({eta}{sup 5}-C{sub 5}Me{sub 5}){sub 2} TiR (R = Me, Et): Insertion versus {beta}-hydrogen transfer and olefin extrusion. Preparation of the paramagnetic titanium alkoxide, iminoacyl, acyl, vinyl, and azomethide complexes ({eta}{sup 5}-C{sub 5}Me{sub 5}){sub 2} TiX and oxidation of these with PbCl{sub 2} to the diamagnetic tetravalent derivatives ({eta}{sup 5}-C{sub 5}Me{sub 5}){sub 2}Ti(X)Cl

Titanium alkyls Cp*{sub 2}TiR (1, R = Me; 2, R = Et) were compared in their behavior toward a range of reactive molecules. Cp{sup *}{sub 2}TiR-L could be formed by the reaction of 1 and ME{sub 3}CC{triple_bond}N. Active-hydrogen-containing substrates HX (X = O{sub 2}C(H)Me{sub 2}, OEt, C{triple_bond}CMe), produced Cp*{sub 2}TiX and RH. Polar, unsaturated molecules like Me{sub 3}CN{triple_bond}C, CO, and paraformaldehyde inserted to give Cp*{sub 2}Ti({eta}{sup 2}-C(R){double_bond}NCMe{sub 3}), Cp*{sub 2}Ti({eta}{sup 2}-C(O)R), and Cp*{sub 2}TiOCH{sub 2}R for both 1 and 2. 35 refs., 3 tabs.
