Abstract

Chemical processes are disclosed that act to both regenerate and create new catalyst for iron salt catalyzed Kharasch coupling reactions during the process of creating halogenated hydrocarbons. Such processes include loading a reactor with a quantity of Fe(0) metal such as iron wire, supplying CCl4 to the reactor, supplying a phosphate compound to the reactor, supplying an alkene to the reactor, and supplying a carbonyl of Fe(0) to the reactor.
