WebThe “classical approaches” for the synthesis of these arenes are based on the direct substitution onto an existing benzene scaffolds. The most common strategies based on this approach involve: electrophilic or nucleophilic substitution, metal-catalyzed coupling reactions, and metalation–functionalization reactions.
WebIn industry, the synthesis of deuterated benzene can be divided into three categories: hydrogen-deuterium exchange method, heavy hydrogenation of introduced halogen and polymerization synthesis method.
