Rapid Synthesis of 2,4,6-Triarylpyridinium Tetrafluoroborates under the Microwave Irradiation and Sovlent-Free Conditions

2,4,6-Triarylpyridinium tetrafluoroborates have been rapidly synthesized in good yields under microwave irradiation and sovlent-free conditons, and characterized by NMR, IR spectra and elemental analyses. Meanwhile, the crystals of compound 4f were obtained and determined by X-ray single-crystal diffraction. The crystal of the compound belongs to orthorhombic system with space group Pbca, a＝2.1050(2) nm, b＝1.64360(17) nm, c＝2.9209(3) nm, α＝β＝90.00°, γ＝90.00°, D_c＝1.276 g•cm^－3, V＝10.1057(17) nm^－3, and Z＝16.
