Abstract

Abstract: 7, 8-Dimethylene-1, 3, 5-cyclooctatriene (4) has been synthesized from 1, 2-bis (hydroxymethyl) cycloocta-tetraene (6), by conversion to 1, 2-bis (bromomethyl) cyclooctatetraene (7) and subsequent zinc reduction. Treat-ment of 7 with potassium t- butoxide led to 7-methylene-8-bromomethylene-l, 3, 5-cyclooctatriene@), while similar treatment of 1, 2-bis (chloromethyl) cyclooctatetraene (9) gave 7-methylene-8- ...
