Title: Preparation of macrocycles with high carbon content: Toward the synthesis of endohedral metal fullerene complexes

Abstract

This research is focused on the synthesis of macrocycles with high carbon content for the purpose of total synthesis of fullerenes or fullerene-like structures with the ultimate goal of obtaining endohedral metal complexes of fullerene C{sub 60}. Toward this goal, the authors have utilized organometallic chemistry to synthesize novel cyclophanes such as 1 which are constituted primarily of acetylenic units. The authors believe such macrocycles may be C{sub 60} precursors since studies have shown that acetylenic macrocycles form fullerenes in the gas phase. The authors have synthesized macrocycle 1 using a highly convergent route from commercially available starting materials. The macrocycle 1 is produced from copper (I) catalyzed coupling of 2 which is obtained in turn by the coupling of the copper acetylide 3 with 4. The suitability of macrocycles such as 1 for fullerene precursors is currently under investigation.
