which has added 1,4 to the rhodium(I)β-ketoenolate ring. Similar complexes result from the reactions of [Rh(acac)(L)(C4F6)](L = C2H4 or cyclo-octene) and hexafluorobut-2-yne. Reactions of hexafluorobut-2-yne with the 4-aminopent-3-en-2-iminato(apemino-) complexes [RhHN C(Me)CHC(Me)NH}L2](L = C2H4; L2= cyclo-octa- 1,5-dieno), however, afford the hexakis(trifluoromethyl)benzene complex [Rh(apemino·C4F6)η4-C6(CF3)6}]
化合物[Rh(acac)(C 2 H 4)2 ]和[Rh(dpm)(C 2 H 4)2 ]与大约六氟丁-2-炔反应。–78°C分别给出[Rh(acac)(C 2 H 4)(C 4 F 6)]和[Rh(dpm)(C 2 H 4)(C 4 F 6)](acac =戊烷-2 ,4-二酸酯; dpm = 2,2,6,6-四甲基庚烷-3,5-二酸酯)。类似地,[Rh(acac)(C 8 H 14)2 ]与六氟丁-2-炔在约4-6 ℃反应。–78°C给出[Rh(acac)(C 8H 14)(C 4 F 6)](C 8 H 14 =环辛烯)。[Rh(dpm)(C 2 H 4)(C 4 F 6)]中的乙烯配体在溶液中随该配体的旋转而表现出动态行为,其可被烯烃L =环辛烯,环庚烯从铑中置换出来,丙烯和顺式-丁-2-烯得到配合物[Rh(dpm)(L)(C 4 F 6)]。[Rh(dpm)(C 2 H 4)(C
