  Manganese(II) Alkyl/π-Allyl Complexes Resistant to Ligand Redistribution

  摘要：

  The reaction of [Li(THF)(4)][(Mn{C-(SiMe3)(3)})(3)(mu-Cl)(4)(THF)] (1) with K(allyl(TMS2)) (allyl(TMS2) = 1,3-C3H3(SiMe3)(2)) afforded [(eta(3)-allyl(TIMS2))Mn{C(SiMe3)(3)}-{ClLi(THF)(3)}] (2). Attempted sublimation of 2 yielded [(eta(3)-allyl(TMS2))Mn{C(SiMe3)(3)}(THF)] (3), indicating that 2 extrudes LiCl at elevated temperatures. Additionally, LiCl in 2 was displaced by reaction with PMe3, quinuclidine, and dmap (dmap = 4-(dimethylamino)pyridine), providing [(eta(3)-allyl(TMS2))Mn{C(SiMe3)(3)}(L)] (L = PMe3 (4), quinuclidine (5), dmap (6)). Treatment of PMe3 complex 4 with BPh3 yielded bright red [(allyl(TMS2))Mn{C(SiMe3)(3)}] (7) accompanied by a precipitate of Ph3B(PMe3). Mixed alkyl/pi-ally manganese(II) complexes 2-7 are pyrophoric red solids with a high-spin d(5) configuration, and all were crystallographically characterized. In the solid-state structures, the allyl ligands in 2-6 adopt a syn,syn configuration, whereas in base-free 7, the allyl ligand has a syn,anti configuration. Complexes 4, 5, and 7 sublimed cleanly (5 mTorr) at 70, 90, and 50 degrees C, respectively. Complex 4 exhibited a particularly favorable combination of volatility and thermal stability, given that its appearance and powder X-ray diffraction pattern were unchanged after 24 h in a sealed flask at 100 degrees C. Compounds 2-7 are the first high-spin d(5) mixed alkyl/allyl complexes, and 7 is the first room-temperature-stable example of a mononuclear transition-metal complex bearing only alkyl and allyl ligands.
