摘要：

Treatment of the manganese dialkyl MnR2 [R = CH(SiMe3)2], prepared from anhydrous MnCl2 and LiR in Et2O, with tetrahydrofuran (THF), yielded the crystalline complex [MnR2(THF)] (1). It was also obtained from MnCl2 and [MgR(μ-Cl)(THF)]2 in THF. Treatment of 1 with (Me2PCH2)2 (DMPE) afforded [MnR2(DMPE)] (2). Selected bond lengths and angles for 1 (2 in brackets) are MnC 2.06(2) [2.17(1)] and MnO 2.19(2) [MnP 2.775(4)] Å, CMnC′ 160.1(9) [141.4(7)], OMnC 100.0(6)° [PMnC 98.7(4) and 112.1(3), and PMnP′ 74.4(1)°]. Compound 1 is also a monomer in n-C5H12. Its magnetic behaviour is consistent with high spin Mn(II), and its EPR spectrum (like that of 2) at ambient temperature in THF showed a broad singlet (gav = 2.005 for 1). Various reactions of complex 1 have been carried out: PMe3 gave [MnR2(PMe3)2], ArOH gave Mn(OAr)2 (Ar = C6H2Bu2t-2,6-Me-4), and M[N(SiMe3)2]2 gave MR2(M = Sn or Pb) (providing particularly convenient route to these Group 14 metal alkyls). © 1990.
