Abstract

The trimer of benzo-18-crown-6-has been prepared by our group by electrolysis in acetonitrile with isolated yield of 20 % by using the present recipe (case of an insoluble product)-300 MHz NMR (CD 3 CN) δ ppm (TMS) 7.84 (s,6H), 4.37–4.41 (m,12H), 4.04–4.07 (m,12H), 3.82–3.85 (m,12H), 3.74–3.77 (m,12H); mp (methylene chloride - pentane): 160°C. Work presently in progress shows also that anodic trimerization of benzo -21- crown 7 is also feasible.
