| Abstract: | Complex Catalysis with Technetium Compounds. Hydroformylation with Technetiumcarbonyl Catalysts The hydroformylation reaction of cyclohexene ( 1 ), propene ( 2 ) and 1-octene ( 3 ) was studied using Tc2(CO)10 and Tc(CO)10/P(n-C4H9)3, resp., as catalysts in solution. For comparison experiments have also been made with Mn2(CO)10, Mn2(CO)10/P(n-C4H9)3 and Re2(CO)10/P(n-C4H9)3 as catalysts for the hydroformylation of 1 . There is always a competition between hydrogenation and hydroformylation. Tc2(CO)10/P(n-C4H9)3 gave the best results in activity and selectivity within the subgroup VII complexes studied, but is a rather poor catalyst compared with the cobalt or rhodium compounds. |
