Synthesis of dicopper [3]-catenates and [3]-catenands by acetylenic oxidative coupling. Preparation and study of corresponding homodimetallic [3]-catenates (Ag+, Zn2+, Co2+, and Ni2+)

Dietrich-Buchecker, Christiane O.,Hemmert, Catherine,Khémiss, Abdel-Kader,Sauvage, Jean-Pierre

, p. 8002 - 8008 (2007/10/02)

[3]-Catenates have been prepared in good yield by double acetylenic oxidative coupling from a terminal diyne threaded into a preformed ring. The central macrocyle is a 44-membered ring, whereas the peripheral subunits consist of 27- or 30-membered rings;
