Substitution nucléophile aromatique d'aryllithiumtricarbonylchrome sur des méthoxy- et chloro-arenetricarbonylchrome
摘要:
Treatment of veratroletricarbonylchromium with n-BuLi and ClS(CHMe2)3 or para-chlorotoluenetricarbonylchromium complexes with n-BuLi yields unexpected dinuclear complexes 4 and 6 via a cine nucleophilic aromatic substitution of a methoxy or a chloro group by an aryllithiumtricarbonylchromium complex. The structure of one of these complexes 4 is reported which shows the loss of a methoxy group and a 34-degrees torsional angle between the aromatic rings.
