We successfully synthesze a series of fluorine-containing pyridine[4-RfCH2OCH2 -pyridine, Rf = CF2H、C2F4H、C4F8H、C6F12H]、[3-RfCH2OCH2-pyridine,Rf = CF2H、CF3、C2F4H、C2F5、C3F7、C4F8H、C6F12H]. Because there is a lone pair of electrons on the nitrogen, the chemical properties of pyridine are like tertiary amines, as the basic and can react with acid. By this characteristic, we can react 4-RfCH2OCH2-pyridine[Rf = CF2H、CF3、C2F4H] with hydrogen halide to generate the pyridium Salt. In addition, there are N-H, C=O and S=O functional groups in the saccharin, so saccharin is a good donor and accept or the N-H functional group, strong acidity, is donor, it can protonated N on the pyridine. The C=O and S=O functional groups are good accepter, by these characteristic saccharin can react with pyridine to generate the synthon compound. In addition, through solid phase synthesis,we react 4-CF2HCH2OCH2-pyridium iodine with Tin iodine to generate the new perovskite 4-CF2CH2OCH2-pyridinium triiodotin. The characteristics of new compounds we synthesize were mesured by NMR、FT-IR、GC-MS and Powder-XRD .
