Abstract

Some pre-activated rhodium bipyridine complexes cis-[Rh(N–N)2Cl2]Cl are catalytically active at temperatures between 5 and 20 C in the transfer hydrogenation from propan-2-ol to N@N, C@O or C@C double bond. Azobenzene is reduced at 20 C with a conversion of 54.2%, while acetophenone is hydrogenated for 34.1%. The C@C double bond of benzylidenacetone is reduced even at 5 C with a conversion of 17.2%, while a complete conversion is obtained at 40 C.
