Construction of Interlocking and Threaded Rings Using Two Different Transition Metals as Templating and Connecting Centers: Catenanes and Rotaxanes Incorporating Ru(terpy)2-Units in Their Framework

摘要: This work describes a new method for the preparation of metal-containing catenanes and rotaxanes, using pure coordination chemistry, by stepwise reaction organic fragments with two different transition metals. The key compound contains terpyridine (terpy) ligands one diphenylphenanthroline (dpp) moiety was prepared in high yield alkylation 2,9-bis(hydroxyphenyl)-1,10-phenanthroline 5-(3-methanosulfonyl-1-propyl)-5‘‘-methyl-2,2‘:6‘,2‘‘-terpyridine. Reaction this polyfunctional ligand 1 equiv dpp-containing 30-membered macrocycle Cu(I) as template led to threaded Cu(dpp)2+-type precursor complex (P). Due affinity dpp ligands, is selective, no competition terpy units metal takes place. Thus, free moieties suitable further reaction. Ru(II) used build stoppers or clip due stability Ru(terpy)2...
