Abstract:
Unlike silanolates [SiR3O]- (R = alkyl, aryl), which have been intensely studied, the heavier derivatives [SiR3E]- (E = S, Se, Te) have been much less examined. Among such species, virtually nothing is known about perfluoroalkyl-substituted silylchalcogenolates. In this contribution, a convenient synthesis of tris(pentafluoroethyl)silylchalcogenolate salts [{(Et2N)3P═N}3PN(H)Bu][Si(C2F5)3E] (E = S, Se, Te; Bu = tert-butyl) is presented. All representatives were isolated and fully characterized by multinuclear NMR spectroscopy, IR spectroscopy, mass spectrometry, elemental analysis, and X-ray diffraction studies. Furthermore, first reactivity studies of these novel species toward selected metal halide complexes were performed. In this course, metal complexes [HgPh{SSi(C2F5)3}] (2) and [Au(PPh3){SSi(C2F5)3}] (3) were isolated and characterized.
