  Half-Sandwich Halide, Alkyl, Hydride, and Related Complexes of Iron Containing the Bulky Diphosphine 1,2-Bis(diisopropylphosphino)ethane. Crystal Structure of [FeH2(C5Me5)(dippe)][BPh4]

  摘要：

  The four-coordinate iron phosphine complex [FeCl2(dippe)] (dippe = 1,2-bis(diisopropylphosphino)ethane) reacts with LiC5H5 or LiC5Me5 in thf, yielding the corresponding half-sandwich derivatives [FeCI(C5H5)(dippe)] (1) or [FeCI(C5Me5)(dippe)] (2), respectively. These complexes react with Grignard reagents RMgCl to give [FeR(C5H5)(dippe)] (R = Me (3) or CH2SiMe3 (4)) or [FeR(C5Me5)(dippe)] (R = Me (5)). If (i)PrMgCl is used, the monohydrides [FeH(C5H5)(dippe)] (6) and [FeH(C5Me5)(dippe)] (7) are obtained, presumably through a beta-elimination reaction. These hydrides are also prepared by reaction between the corresponding chloro complexes and Li[HBEt3] in thf. The monohydrides 6 and 7 undergo a one-electron oxidation by reaction with [Fe(C5H5)2][PF6], yielding the 17-electron hydrides [FeH(C5H5)(dippe)]+ and [FeH(C5Me5)(dippe)]+, isolable as tetraphenylborate salts, {FeH(C5H5)(dippe)][BPh4] (8) and [FeH(C5Me5)(dippe)][BPh4] (9). The reaction of 1 or 2 with dihydrogen in methanol, followed by addition of Na[BPh4] yielded the dihydrides [FeH2(C5H5)(dippe)][BPh4] (10) and [FeH2(C5Me5)(dippe)][BPh4] (11), respectively. No equilibrium dihydride reversible dihydrogen has been detected in these complexes, and therefore, they must be regarded as organoiron(IV) species. The crystal structure of 11 has been determined. Crystal data: monoclinic system, space group P2(1)/n, cell parameters a = 14.277(4) angstrom, b = 21.388(6) angstrom, c = 14.619(6) angstrom, beta = 101.07(3)-degrees, and Z = 4. It suggests a transoid arrangement of hydride ligands, consistent with the formulation as an iron(IV) dihydride. The vinylidene complexes [Fe=C=CHPh(C5H5)(dippe)][BPh4] (12) and [Fe=C=CHPh(C5Me5)(dippe)][BPh4] (13) were also prepared and characterized. Deprotonation of these vinylidene complexes yielded the alkynyl derivatives [Fe(C=CPh)(C5H5)(dippe)] (14) and [Fe(C=CPh)(C5H5)(dippe)] (15). All the compounds were characterized by NMR, IR, and microanalysis.
