Thorium Group 14 compounds and complexes

When a cyclohexane solution of thorium complex IV-16 (Scheme IV-15) containing neopentyl ligands is heated one of the ligands can be eliminated and cyclometalation of a remaining alkyl groups proceeds [25a], Metallacycle IV-17 thus formed metalates intermolecularly tetramethylsilane. The reaction does not stop when compound IV-18 is formed, and cyclometalated complex IV-19 can be obtained. The thorium complex also readily activates methane. It should be noted that formally thorium is not a low-valent ion in these reactions. [Pg.154]
