The (β-ketiminato)rhodium complex [Rh{κ2-(N,O)-(tBu) (O)CCHC(tBu)N(C6F5)}(cod)] (1) [cod = (1Z,5Z)-1,5- cyclooctadiene] and (β-diketiminato)rhodium complexes [Rh{κ 2-(N,N)-(Ar)NC(Me)CHC(Me)N(Ar)}(L1)(L2)] [2: Ar = C6F5, (L1)(L2) = cod; 3: Ar = C6F5, L1 = L2 = C2H 4; 4: Ar = C6F5, L1 = L2 = CNtBu; 5: Ar = 2,6-MeC6H3, L1 = L2 = CNtBu; 6a: Ar = C6F5, L1 = L2 = CO; 7a: Ar = C6F5, L1 = CO, L2 = NCMe; 8a: Ar = C6F5, L1 = CO, L2 = PEt3; 9a: Ar = C6F5, L1 = CO, L 2 = NH3] were synthesized. Treatment of [Rh{κ2-(N,N)-(C6F5)NC(Me)CHC(Me)N(C 6F5)}(CO)(NCMe)] (7a) with tertiary silanes HSiR 3 gave the (β-diketiminato)(hydrido)(silyl)rhodium complexes [Rh{κ2-(N,N)-(C6F5)NC(Me)CHC(Me)N(C 6F5)}(H)(SiR3)(CO)] (10a: R = Me; 11: R = Et; 12: R = iPr; 13: R = Ph; 14: R = OMe; 15: R = OEt). When using an excess amount of HSiMe3 the dihydridobis(silyl) complex [Rh{κ2-(N, N)-(C6F5)NC(Me)CHC(Me)N(C6F5)}(H) 2(SiMe3)2] (16) was formed in addition to 10a. A series of rhodium complexes with a fluorinated β-diketiminato ligand as well as a fluorinated β-ketiminato ligand has been synthesized. Treatment of [Rh{κ2-(N,N)-(C6F5)NC(Me)CHC(Me) N(C6F5)}(CO)(NCMe)] with tertiary silanes HSiR3 (R = Me, Et, iPr, Ph, OMe, OEt) gave the (β-diketiminato)(hydrido)(silyl) rhodium complexes [Rh{κ2-(N,N)-(C6F 5)NC(Me)CHC(Me)N(C6F5)}(H)(SiR 3)(CO)].
