Three selected examples for the use of unusual wording to describe the organometallic chemistry of Group 4 metallocenes are explained and discussed. The term "tuck(ed)in" concerns the behavior of decamethyltitanocene [(C 5 Me 5) 2 Ti]a nd similar complexes in whicho ne or two methyl groups form the titanium hydride complex [(C 5 Me 5)-(C 5 Me 4 CH 2)TiH] or other hydride complexes by C À Hactivation. In the so-called "merry-go-round reaction" the rearrangement of Ca toms bound to titanium in organometallic molecules is described whichc orresponds to the rotation of two Catoms along with arotation of the six-membered ring in ad ihydroindenyl moiety at titanium. In the third example "migration" or "tobogganing" concerns the "sliding" of titanocene along the chain of alinear polyyne by coordination to one or more triple bonds.Inall these reactions changes of the coordination mode of the metal at Cp or substrate ligands by intramolecular dynamics occur.

Drei Beispiele fürd ie Verwendung einfacher und anschaulicher Benennungen in der Organometallchemie von Metallocen-Komplexen der Gruppe 4w erden erklärt und diskutiert. Die Bezeichnung "tuck(ed)-in" betrifft das Verhalten des Decamethyltitanocens [(C 5 Me 5) 2 Ti]o der ähnlicher Komplexe,b ei dem eine oder zwei Methylgruppen Titanhydrid-Komplexew ie [(C 5 Me 5)(C 5 Me 4 CH 2)TiH] oder andere Hydridkomplexed urch C-H-Aktivierung bilden. In der "merrygo-round-reaction" wird die Umlagerung von C-Atomen am Titan in Organometallmolekülen beschrieben, bei der eine Rotation von zwei C-Atomen mit einer Rotation der sechsgliedrigen Dihydroindenyl-Einheit am Titan erfolgt. Das dritte Beispiel "migration" oder "tobogganing" betrifft das "sliding" von Titanocen an der Kette eines linearen Polyins durchK oordinierung von einer oder mehreren Dreifachbindungen. In allen diesen Reaktionen wechselt die Koordinationsweise des Metalls am Cp-oder dem Substratliganden, was mit einer intramolekularen Dynamik verbunden ist.
