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.....»»
How mantle hydration changes over the lifetime of a subduction zone
Because of interactions with Earth's hot mantle, water-logged oceanic plates release water as they slide beneath less dense overriding plates in subduction zones. This water rises and hydrates the mantle above it, contributing to the formation of vol.....»»
