A new β-CD inclusion complex with a seven-membered ring bridged organocobaloxime

This work demonstrates that by providing a confined environment, the cyclodextrin binding promotes the debromination reaction of aqua-(4-bromobutyl)cobaloxime to form a novel seven membered ring aqua(O-tetramethylene-CHEL)cobaloxime, which is included in the β-CD cavity and could not be prepared in the absence of β-cyclodextrin.

Graphical abstractX-ray structure and 1H NMR have been applied to characterize a novel seven-membered ring bridged organocobaloxime/β-CD inclusion complex, which has been formed in a β-CD induced debromination reaction.Figure optionsDownload full-size imageDownload as PowerPoint slideFigure optionsDownload full-size imageDownload as PowerPoint slide
