Chain–ring isomerism vs. carbon–carbon coupling on two(tetracarbonyliron)-γ-ketoesters: cis-[Fe(COR)(COCOR′)(CO)4](R = Me, R′= OMe; R = OMe; R′= Me)
Abstract
Ferra-γ-ketoesters 1 and 2 induce thermally either a carbon–carbon coupling process or a chain–ring isomerization; the orientation of the reaction likely depends on the proximity of the ester group to the metal centre.
