A collaboration with Marco Cecchini’s group, this is a mixed computational and experimental attempt to rationalize why specific nitro compounds change the kinetic orders of some Brønsted acid catalyzed reactions. The model successfully predicts that sulphate esters should behave similarly. It has been published in Chemistry – A European Journal as part of the EuChemS special issue. Congrats to Marian and Ed for what ended up being the last of their many papers in the group! Also thanks to the Cecchini group for their endurance.
