MIT chemists have devised a new chemical reaction that allows them to synthesize a phosphorus-containing ring, using a catalyst to add phosphorus to simple organic compounds called alkenes. Their reaction, which yields a ring containing two carbon atoms and one phosphorus atom, can be performed at normal temperature and pressure, and makes use of a novel “spring-loaded” phosphorus-containing molecule that supplies the phosphorus atom. “This is a rare example of a discovery of a new catalytic reaction, and it opens up a real wealth of new opportunities to do chemistry…
