The vinyl C-H bond of tetramethylfulvene is activated in the presence of [(C5Me5)2LuH]x, 1, to form a vinyl organolutetium complex, (C5Me5)2Lu(CH=C5Me4), 2. Also formed in the reaction is the tuck-over complex, (C5Me5)2Lu(μ-H)(μ-η1:η5-CH2C5Me4)Lu(C5Me5), 3, containing a (CH2C5Me4)2- moiety long postulated to exist in organolutetium chemistry but never crystallographically characterized. Evidence for these C-H bond activations by a (C5Me5)3Lu intermediate, 4, is presented. Complex 3 can also be made in high yield by thermolysis of 1. Under H2, 1 catalytically hydrogenates TMF to C5Me5H. Copyright
