Synthesis and Characterization of the 1 : 1-Adducts of In(C6F5)3 with Acetonitrile, Glyme, and DMAP (DMAP = 4-(N,N-dimethylamino)pyridine), and [PNP][In(C6F5)4] (PNP = bis(triphenylphosphinanyliden)immonium) - the Crystal Structure of [PNP][In(C6F5)4]
摘要:
In(C6F5)(3). CH3CN and In(C6F5)(3). glyme were synthesized from InCl3 and Cd(C6F5)(2) in CH3CN or glyme in 43% and 35% yield, respectively. Replacement of CH3CN or (C2H5)(2)O by DMAP yielded the corresponding 1:1-adduct.[PNP][In(C6F5)(4)] was best prepared from the corresponding cesium salt which was best synthesized from the reaction of stoichiometric amounts of In(C6F5)(3). CH3CN, (CH3)(3) SiC6F5 and CsF in good yield.[PNP][In(C6F5)4] crystallizes in the triclinic space group P (1) over bar, a = 1104.9(4) pm, b = 1442.4(6) pm, c = 1833.8(8) pm, alpha = 110.87(2)degrees, beta = 92.04(3)degrees, gamma = 96.55(3)degrees, Z = 2.
