Catalytic H/D-exchange reactions were studied with [Ru(dtbpmp)(η2-H2)(H)2] (1) as catalyst. Under mild reaction conditions (25–75 °C) a wide range of arenes and olefins undergo H/D exchange with [D6]benzene. A preference for protons at sp2 carbons was observed with conversions up to >90 % and significant regioselectivity in certain cases. For more reaction insights NMR-based kinetic studies were performed
