Aryl radical formation by aryl halide bond cleavage by a N-heterocyclic carbene catalyst
Aryl halides with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a chemical reaction that generates a highly reactive aryl.....»»
Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»
