Preparation of macrocycles with high carbon content: Toward the synthesis of endohedral metal fullerene complexes
- Univ. of California, Los Angeles, CA (United States)
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.
