  Toward charge-neutral ‘soft scorpionates’: Coordination chemistry and Lewis acid promoted isomerization of tris(1-organo-imidazol-2-ylthio)methanes

  摘要：

  Two tris(1-organo-imidazol-2-ylthio)methanes, HC(S-tim(R))(3) (R = organo = methyl, tert-butyl), have been prepared by a triphasic reaction between chloroform, the appropriate heterocycle, and saturated aqueous solutions of Na2CO3, in the presence of a phase transfer agent, (NBu4)(Br). These ligands have been characterized both spectroscopically and by single crystal X-ray diffraction. The reaction chemistry of these potentially N, N, N-tripodal ligands with AgBF4 was also explored where simple 1:1 coordination complexes could be isolated from reactions performed in THF solution at room temperature. The derivative {Ag[HC(S-tim(Me))(3)]}(BF4) was structurally characterized which showed that the ligand binds in a mu-kappa N-2,kappa N-1-mode to give a coordination polymer with an interesting layered supramolecular structure. Surprisingly, heating CH3CN solutions of the silver complexes at reflux resulted in decomposition of the complex and concomitant isomerization of the ligands to give metal-free tris(3-organo-1-imidazole-2-thione) methane, HC(N-imt(R))(3); the heretofore elusive charge-neutral analogues of the well-studied 'soft scorpionate' Tm-R anions. The solution isomerization of HC(S-tim(R))(3) to HC( N-imt(R))(3) was found to be general, occurring in a variety of solvents with any of a host of different Lewis acids [para-toluenesulfonic acid, KPF6, and M(CO)(5)Br (M = Mn, Re)] but did not occur by heating in the absence of Lewis acid. The compound HC(N-imt(Me))(3) exhibited unusually low solubility in common organic solvents. Single crystal X-ray diffraction of HC(N-imt(Me))(3) revealed a remarkable honeycomb supramolecular structure with ca. 5 angstrom channels filled with solvent. The robust nature of this solid is a result of strong dipolar stacking interactions of molecules into polymer chains bolstered by concerted pi-pi and CH-pi interactions involving the heterocycles, holding the chains together in the remaining two dimensions.
