respectively. Complex 8a slowly reacts with more CH3I to give [PEt3Me][Rh(I)2(COCH3)(4-C5NF4)(PEt3)](9). On heating a solution of 7a, the complex trans-[RhI(CO)(PEt3)2] (10) and the C-C coupled product 4-methyltetrafluoropyridine (11) have been obtained. Complex 8a also forms 10 at elevated temperatures in the presence of CO together with the new ketone 4-acetyltetrafluoropyridine (12). The structures of the
[RhH(PEt3)3](1)或[RhH(PEt3)4](2)与五
氟吡啶或2,3,5,6-四
氟吡啶的反应得到活化产物[Rh(4-C5NF4)(PEt3)3 ](3)。用CO,13CO或CNtBu处理3会形成反式[Rh(4-C5NF4)(CO)(PEt3)2](4a),反式[Rh(4-C5NF4)(13CO)(PEt3)2 ](4b)和反式[Rh(4-C5NF4)(CNtBu)(PEt3)2](5)。
铑(III)化合物反-[RhI(
CH3)(4-C5NF4)(PEt3)2](6a)和反-[RhI(13 )(4-C5NF4)(PEt3)2](6b)可通过以下途径获得3与 I或13 I的反应。在CO或13CO存在下,这些络合物转化为反式[RhI( )(4-C5NF4)(CO)(PEt3)2](7a),反式[RhI(13 )(4-C5NF4)(CO) (PEt3)2](7b)和
