The synthesis of rhodium complexes with weakly binding highly fluorinated benzene ligands is described: 1,2,3‐F 3 C 6 H 3 , 1,2,3,4‐F 4 C 6 H 2 and 1,2,3,4,5‐F 5 C 6 H are shown to bind with cationic [Rh(Cy 2 P(CH 2 ) x PCy 2 )] + 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(CF 3 ) 3 } 4 ] − anion.
