Summary
The synthesis of [Rh(NBD){P(p-RC6H4)3}2]A complexes (A=ClO −4 or BPh −4 ; R=Cl, F, Me or MeO) is described. Treatment of these complexes with molecular hydrogen leads to the isolation of [RhH2{P(p-RC6H4)3}2(OCMe2)2]ClO4 or Rh{P(p-RC6H4)3}2PhBPh3. These latter complexes contain tetraphenylborate coordinated to the metalvia arene interaction. [Rh(CO)3{P(p-RC6H4)3}2]ClO4 complexes have been isolated by carbonylations. The use of these complexes as homogeneous hydroformylation catalysts is also briefly investigated.
