摘要

This paper describes the cyclotrimerization reaction of di (2-azulenyl) acetylenes (2a, b) catalyzed by Co2 (CO) 8 to produce hexa (2-azulenyl) benzene derivatives (1a, b). The cyclooligomerization of 2a and 2b utilizing CpCo (CO) 2 as a catalyst produced (η5- cyclopentadienyl)[tetra (2-azulenyl) cyclobutadiene] cobalt complexes (3a, b). The redox behavior of hexakis (6-octyl-2-azulenyl) benzene (1b), bis (6-octyl-2-azulenyl) acetylene ( ...
