  One step conversion of perrhenate into an Re(IV) complex: synthesis and molecular structure of trans-[ReCl4(PMePh2)2]

  摘要：

  KReO4 reacts in a one-pot reaction with 4 mole of diphenylmethylphosphine and aqueous hydrochloric acid in boiling ethanol to yield trans-tetrachloro-bis (diphenylmethylphosphine) rhenium (1) in high yield. The almost quantitative, direct reduction of perrhenate to Re(IV) by PPh2Me/HCl has been observed for the first time. Bright red 1 can be crystallized from chloroform/hexane to give bright red plates. Crystals of 1 are triclinic with a=8.898(6), b=9.543(4), c=9.713(3) Angstrom, alpha=66.68(2), beta=88.54(4), gamma=63.10(3)degrees, Z=1 and D-obs=1.83 g cm(-3). The structure was solved from 2327 diffraction data (F-o(2) greater than or equal to 3 sigma(F-o(2))) collected at 20(2)degrees and refined to R=0.029 (R-w=0.039).

  [K(Q)] [ReH2(PMePh2)(2)}(2)(mu -H)(3)] is prepared by treatment of ReH2(PMePh2)(2)}(2)(mu -H)(4) with potassium hydride and a crown ether (Q = 18-crown-6 or 1,10-diaza-18-crown-6). The [K(1,10 diaza-18-crown-6)](+) salt contains NH . . . HRe protonic-hydridic bonds and has been characterized by P-31 NMR, variable temperature H-1 NMR, IR, and X-ray crystallography. The pK(alpha)(THF) = 33 of ReH2(PMePh2)(2)}(2)(mu -H)(4) was determined on the basis of its reaction with [K(2,2,2-crypt)][PO(OEt)(2)NPh].[GRAPHICS]
