Abstract
Four sequential products have been spectrally detected in the reduction by sodium of dicyclopenta-dienyltitanium(IV) dichloride: [(π-Cp)2TiCl]2, [(π-Cp)2Ti]1–2, [(π-Cp)(C5H4)TiH]x, and (π-Cp)(C5H4)TiH2Ti(C5H4)(π-Cp)(“stable titanocene”); the second of these reacts rapidly and reversibly with N2 to give a dark blue complex reducible to ammonia and appears to catalyse the cyclopentadienyltitanium-promoted rapid, room temperature-atmospeheric pressure hydrogenation of olefins.Keywords
