Parallèllement, Ru(? 6 -arène)][PF 6 ], Pouvant servir de briques élémentaires pour l'élaboration d'architectures moléculaires complexes, pour lesquels l'arène est un noyau benzénique, nous avons synthétisés et caractérisés une nouvelle famille de complexes sandwichsPF 6 ]) et naphthalénique substitué en positions 1

*. Cp, +. Ru, and . Agit-comme-un-interrupteur-moléculaire, Complexé sur le noyau disubstitué, il coupe l'interaction électronique entre les deux extrémités au travers du système ?

. Cependant, cette première démonstration d'un réarrangement haptotropique induit par processus redox valide notre approche vers les composants moléculaires

{. Le-complexe-homobinucléaire, 4-C 10 H 6 ) (4.12) a été préparé en deux étapes par activation d'alcynes vrais à partir de (? 2 -dppe)(? 5 -Cp*)FeCl et du 1, -diéthynylnaphthalène via le dérivé bis-vinylidène [{(? 2 -dppe)(? 5 -Cp*)Fe=C=CH-} 2

. Ru, La caractérisation spectroscopique, analytique et structurale indique que la réaction de complexation est régiosélective et que le greffon [(? 5 -Cp*)Ru] + est lié au noyau libre de l'espaceur 1,4-diéthynylnaphthalène
