Yttrium and lanthanum hydrides [(C(5)Me(5))(2)LnH](2) are active catalysts for the oligomerisation of 2-cycloalken-1-ones; the average degree of oligomerisation increases with temperature.

Several C-H activation reactions with (Cp*2YH)2 (1) are reported. Thermolysis of 1 in n-octane, cyclohexane, or benzene leads to formation of the thermodynamically favored product Cp*2Y(mu-H)(mu-eta1,eta'-CH2C5Me4)YCp*(2). The molecular structure of

Thermolysis of Cp*Zr(COT)R (Cp* = eta5-C5Me5, COT = eta8-C8H8, R = CH2SiMe3, Me) proceeds via a double hydrogen abstraction from a cyclooctatetraene ligand to give RH and Cp*Zr(mu-eta8:eta2-C8H6)ZrCp*(eta4-C8H8) as the kinetic product. Cp*Zr(mu-eta8:
