In October, Michael Supej carved this jack-o’-lantern as part of a pumpkin-carving contest between three friendly academic groups at three different universities: Brett Fors’s group at Cornell University—of which Supej is a member—Luis Campos’s group at Columbia University, and Corey Stephenson’s group at the University of Michigan, Ann Arbor. Although the molecule depicted on the pumpkin is a common ligand for organometallic catalysts, it also has a special connection to Supej’s adviser, Fors. As a graduate student in Stephen Buchwald’s lab at Massachusetts Institute of Technology, Fors synthesized it, and it bears his name, BrettPhos, as is customary in Buchwald’s group.
