| Abstract: | The synthesis of rhodium complexes with weakly binding highly fluorinated benzene ligands is described: 1,2,3-F3C6H3, 1,2,3,4-F4C6H2 and 1,2,3,4,5-F5C6H are shown to bind with cationic Rh(Cy2P(CH2)xPCy2)]+ fragments (x=1, 2). Their structures and reactivity with alkenes, and use in catalysis for promoting the Tishchenko reaction of a simple aldehyde, are demonstrated. Key to the synthesis of these complexes is the highly concentrated reaction conditions and use of the Al{OC(CF3)3}4]− anion. |
