摘要：

(4’-Halomethyl-1’,2’-benzo)-15-crown-5 (RX, 1; X = Cl (a), I (b)) compounds were reacted with Na-[Co(CO)4] (2). The corresponding η1-RC(O)Co(CO)4 (5), η1-RCo(CO)4 (6), and η3-RCo(CO)3 (7) derivatives were obtained through intermediates [(η5-RX)Na] [Co(CO)4] (3) and [(η5-Na+)RC(O)Co(CO)3(X-)] (4). The reactions leading to 7 from 1 were found to be reversible. Derivatives of 4 and 5 were prepared by monosubstitution with PPh3, giving 8 and 9, respectively. The reversibility of the reaction of PhCH2Cl with 2 was also demonstrated. © 1990, American Chemical Society. All rights reserved.
