Congratulations to Connor, who (with help from Amelia) has published a paper in Chem. Commun. on the use of a dibenzophosphole oxide as a redox mediator! Our interest in the dibenzothiophene dioxide redox mediator platform led us to explore a related phosphorus-based system. The phosphine-based mediator coordinates the Cr center relatively more strongly than the sulfur-based one, but loses some specifcity in its binding orientation.
