| Abstract: | Two electron-reduction of the TiIV guanidinate complex (ImDippN)(Xyketguan)TiCl2 gives (η6-ImDippN)(xyketguan)Ti ( 1intra ) and (ImDippN)(Xyketguan)Ti(η6-C6H6) ( 1inter ) (Xyketguan=[(tBuC=N)C(NXylyl)2]−, Xylyl=2,5-dimethylphenyl) in the absence or presence of benzene, respectively. These complexes have been found to hydrogenate monocyclic and polycyclic arenes under relatively mild conditions (150 psi, 80 °C)—the first example of catalytic, homogeneous arene hydrogenation with TON >1 by a Group IV system. |
