Reductive Hexamerization of CO Involving Cooperativity Between Magnesium(I) Reductants and [Mo(CO)6]: Synthesis of Well-Defined Magnesium Benzenehexolate Complexes

The first examples of magnesium benzenehexolate complexes are prepared by reductive hexamerizations of CO, in reactions that are initiated (or catalyzed) by [Mo(CO)6]. These reactions are closely related to Justus von Liebig’s classical 1834 study on the reduction of CO gas with molten potassium, which yields K6C6O6 (amongst other products), by an as yet unknown mechanism.
