1,3,5-triene)iron derivatives [(RC7H7)Fe(CO)3](R = H, OMe, CN, and Ph)(4a–d) have been prepared and a study made of the nucleophilic attack of 2-chlorotropone by their corresponding anions. The tricarbonyl(cycloheptatrienide) iron and tricarbonyl(methoxycycloheptatrienide)iron undergo the reaction to give tricarbonyl[1–4-η-7-(2-oxocyclohepta-1,3,5-trienyl)cyclohepta-1,3,5-triene]iron (7a) and tric
三羰基(1-4-n-环庚-1,3,5-三烯)铁衍生物[(RC 7 H 7)Fe(CO)3 ](R = H,OMe,CN和Ph)(4a – d)已经制备并研究了2-氯托吡酮被它们相应的阴离子的亲核攻击。三羰基(环庚三烯)铁与三羰基(甲氧基环庚三烯)铁发生反应,得到三羰基[1-4-η-7-(2-氧代环庚-1,3,5-三烯基)环庚-1,3,5-三烯]铁(7a)和三羰基[1-4-η-6-甲氧基-7-(2-氧代环庚-1,3,5-三烯基)环庚-1,3,5-三烯]铁(7b), 分别。相反,三羰基(氰基环庚三烯)铁与2-氯代四氢萘酮反应,得到三羰基[1-4-n-6-氰基-7-(2-氧代环庚-1,3,5-三烯基)环庚-1,3,5-三烯]铁(7c)和三羰基[1-4--5--5-氰基-7-(2-氧代环庚-1,3,5-三烯基)环庚-1,3,5-三烯]铁(9c) (7c)/(9c)= 1:5.6的比率。类似地,三羰
