Organolutetium Vinyl and Tuck-Over Complexes via C-H Bond Activation.

The vinyl C-H bond of tetramethylfulvene is activated in the presence of [(C(5)Me(5))(2)LuH](x)(), 1, to form a vinyl organolutetium complex, (C(5)Me(5))(2)Lu(CH=C(5)Me(4)), 2. Also formed in the reaction is the "tuck-over" complex, (C(5)Me(5))(2)Lu(mu-H)(mu-eta(1):eta(5)-CH(2)C(5)Me(4))Lu(C(5)Me(5)), 3, containing a (CH(2)C(5)Me(4))(2-) moiety long postulated to exist in organolutetium chemistry but never crystallographically characterized. Evidence for these C-H bond activations by a "(C(5)Me(5))(3)Lu" intermediate, 4, is presented. Complex 3 can also be made in high yield by thermolysis of 1. Under H(2), 1 catalytically hydrogenates TMF to C(5)Me(5)H.[1]
