摘要

(β-Hydroxyalkyl)-and (β-acetoxyalkyl) cobaloximes can undergo facile acid-catalyzed β- heteroatom exchange with oxygen and nitrogen nucleophiles in an SN1-like mechanism via cationic metal-alkene π-complex intermediates (cobaloxime π-cations). The reaction of cobaloxime π-cations with carbon nucleophiles has not been previously reported. The results reported in this paper demonstrate that cobaloxime π-cations are reasonably good ...
