| Abstract: | A helping hand: Incorporation of Group?2 Lewis acids into a macrocycle appended to a phosphine ligand attached to a rhenium carbonyl complex promotes otherwise unfavorable transformations of coordinated CO (see scheme; M=Ca, Sr). These Lewis acids form relatively weak M?O bonds, thereby enabling release of organic products from the metal center. |
