Chemists have built a new compound in which boron donates and accepts electron pairs when binding two carbon monoxide molecules, a peculiar situation that has the nonmetal main-group element acting like a transition metal (Nature 2015, DOI: 10.1038/nature14489). Until now, no elements outside of the transition metals have been observed to react directly with two or more CO molecules. Holger Braunschweig of Julius Maximilian University, in Würzburg, Germany, led . . .
