P. Gavina et Jp. Sauvage, TRANSITION-METAL TEMPLATE SYNTHESIS OF A ROTAXANE INCORPORATING 2 DIFFERENT COORDINATING UNITS IN ITS THREAD, Tetrahedron letters, 38(20), 1997, pp. 3521-3524
A [2]rotaxane consisting of a molecular string threaded into a coordin
ating ring by means of the template effect of copper (I) has been synt
hesized. The acyclic fragment incorporates two different chelating sit
es (bidentate and terdentate ligands) whereas the macrocycle bears a b
identate chelate. Two bulky groups have been covalently attached at th
e ends of the thread. (C) 1997 Elsevier Science Ltd.
