C-H and C-F bond activation reactions of pentafluorostyrene at rhodium complexes

The rhodium(i) complexes [Rh(Bpin)(PEt3)3] (1), [Rh(H)(PEt3)3] (5) and [Rh(Me)(PEt3)3] (14) were employed in reactions with pentafluorostyrene affording coordination of the olefin and C-F o

Versatile reactivity of a rhodium(i) boryl complex towards ketones and imines

The rhodium(i) boryl complex [Rh(Bpin)(PEt3)3] (1) reacts with the ketones α,α,α-trifluoroacetophenone and 9-fluorenone by insertion of the CO bond to give [Rh{η3-C(CF 3)(OBpin)C6H5}(PEt3)2] (4) and [Rh{η5-C13H8(OBpin)}(PEt 3)2] (6), whereas the reaction with acetophenone leads to the formation of [Rh(H)(PEt3)3] (2), [Rh(OBpin)(PEt 3)3] (3) and (E)-(Ph)CHCHBpin. Treatment of 1 with ketimines generates [Rh{η3-C6H5C(Ph)N(Ph) (Bpin)}(PEt3)2] (7), [Rh{(η3-C 12H8)N(Ph)(Bpin)}(PEt3)2] (8) or [Rh{CPh2N(H)(Bpin)}(PEt3)2] (9). The insertion of aldimines into the Rh-B bond gives access to [Rh[η3- CH{N(C6H13)Bpin}C6H5](PEt 3)2] (11) or [Rh[η3-CH{N(Ph)Bpin}C 6H5](PEt3)2] (12). The latter is converted into the C-H activation product [Rh{(C6H 4)-o-N(Bpin)(CH2Ph)}(PEt3)3] (13). Complex 13 reacts with B2pin2 to yield the boryl complex 1 and the amine PhCH2N(Bpin)(C6H4-o-Bpin).

Synthesis of rhodium(I) boryl complexes: Catalytic N-H activation of anilines and ammonia

The treatment of the rhodium methyl complex [Rh(Me)(PEt3) 3] (1) with diboranes B2[(OR)2]2 gave the 16-valence-electron rhodium(I) boryl complexes [Rh{B(OR) 2}(PEt3)3] [2: (OR)2 = pin = pinacolato, O2C2Me4; 3: (OR)2 = cat = catecholato, O2C6H4; 4: (OR)2 = O2C5H10]. The reactions of 2 and 4 with anilines yielded the amidoboranes HN[B(OR)2](R′) [6: B(OR) 2 = Bpin, R′ = C6F5; 7: B(OR)2 = Bpin, R′ = Ph; 8: B(OR)2 = BO2C5H 10, R′ = Ph] and the rhodium hydrido complex [Rh(H)(PEt 3)3] (5) by N-H activation. The addition of ammonia to 2 resulted in the generation of the amine HN(Bpin)2 (9) as well as 5. The amidoboranes 6, 7, and 9 can also be synthesized catalytically with turnover numbers of 10 for 9 and 8 for 6 and 7. Sixteen-electron RhI boryl complexes are synthesized and used for N-H bond activation reactions of anilines. The treatment of [Rh(Bpin)(PEt3)3] (HBpin = pinacolborane) with NH3 yields the diborylamine HN(Bpin)2. The stoichiometric conversion led to the development of a new catalytic process, and [Rh(Bpin)(PEt3)3] is used as a catalyst to convert NH3 and B2pin2 into HN(Bpin) 2 at room temperature. Copyright
