Discussion of (the) Room-temperature chemical synthesis of dicarbon – open and transparent science.

Wednesday, May 6th, 2020

A little more than a year ago, a ChemRxiv pre-print appeared bearing the title referenced in this post,[1] which immediately piqued my curiosity. The report presented persuasive evidence, in the form of trapping experiments, that dicarbon or C2 had been formed by the following chemical synthesis. Here I describe some of what happened next, since it perhaps gives some insight into the processes of bringing a scientific result into the open.
