Researcher Finds New Way Of Devising Medically Useful Linked Rings Of Atoms Replacing Toxic, Expensive, And Environmentally Unfriendly Old Process

... is that of stitching two ends of a chain of atoms together via a reactive molecule called a "free radical". Virtually all free radical reactions use other chemicals to "initiate" the construction process. Most procedures use one initiator in particular, called "tributyl tin hydride", however it has the fol...
