First Synthesis of Cationic [(η6-arene)Mn(CO)3] Complexes Substituted by Resonance Electron Withdrawing Groups
摘要:
An unprecedented class of cationic [(eta (6)-RCO-arene)Mn(CO)(3)] complexes bearing resonance electron withdrawing groups have been synthesized by a high-yield two-step methodology starting from the neutral (eta (5)-1-chlorocyclohexadienyl)Mn(CO)(3) complex, employing a facile and selective transition-metal-catalyzed carbonylation followed by rearomatization, Definitive spectroscopic details of the novel [(eta (6)-RCO-arene)Mn(CO)(3)](+) products are discussed, and in one case (R = PhO), the structure has been confirmed by X-ray crystallography.
