complex: Milstein's complex, (PNN)RuHCl(CO), catalyzes the efficient reduction of alkyl bromides and chlorides under relatively mild reaction conditions by using propan-2-ol and a base. Sterically hindered tertiary and neopentyl substrates are reduced efficiently, as well as more-functionalized aryl and alkyl bromides. The reaction appears to occur by a radical pathway, and provides an alternative to
