    Process for producing fluorinated organic compounds and fluorinating reagents {PROCESSES FOR THE PRODUCTION OF FLUORINATED ORGANIC COMPOUNDS AND FLUORINATING AGENTS}
    [2] The following are known as fluoronating agents for fluoronating organic compounds:
    [3] HF, KF, IF, IF 5 , tetrabutylammonium fluoride, tris (dimethylamino) sulfur (trimethylsilyl) (TASF), SF 4 , 2ethylaminosulfur trifluoride (DAST), fluorine gas, XeF 2 , CF 3 OF, CH 3 OF, CH 3 COOF, ClO 3 F, N-fluoropyridinium triflate, 1-chloromethyl-4-fluoro-1, 4-diazoniabicyclo [2.2.2 ] Octane bis (tetrafluoroborate), 1-hydroxy-4-fluoro-1, 4-diazoniabicyclo [2.2.2] octane bis (tetrafluoroborate), N-fluorobenzenesulfonate Mead, et al. (Sheppard, WA; Sharts, CM Organic Fluorine Chemistry, 1969, WA Benjamin .: Chambers, RD; Fluorine in Organic Chemistry, 1973, Wiley-Interscience .: Hudlicky, M.

Kobayashi, Fluorinated compounds-Chemistry and their application, 1979 , Kodansha Ltd .: Outline of chemistry / New fluorine chemistry, 1980, Japan Scientific Society Press: N. Ishikawa, T.

Takaoka, Journal of the Society of Synthetic Organic Chemistry, 1979, 37, 606 .: T Umemoto, Journal of the Society of Synthetic Organic Chemistry, 1992, 50, 338: SD Taylor, CC Kotoris, and G. Hum; Tetrahedron, 1999, 55, 12431: Japanese Unexamined Patent Publication No. 1997-227531, etc)
    [4] Among the fluorinating agents, HF, KF, IF, tetrabutyl ammonium fluoride and sulfonium silicate (TASF) have low reactivity. Therefore its use is limited. SF 4 is a toxic gas with a boiling point of -40.4 ° C and is difficult to handle. Fluorine gas is highly reactive, making it difficult to control the reaction. In addition, CF 3 OF, CH 3 COOF and ClO 3 F are reported as explosive gases and must be handled with care.
    [5] Triethyl fluoride 2ethylaminosulfur (DAST), XeF2, N-fluoropyridinium triflate, 1-chloromethyl-4-fluoro-1, 4-diazoniabicyclo [2.2.2] octane bis (tetra Fluoroborate), 1-hydroxy-4-fluoro-1, 4-diazoniabicyclo [2.2.2] octane bis (tetrafluoroborate), N-fluorobenzenesulfonimide, etc. Although easy and selective fluorine is possible, they are expensive and have problems in industrial use.
    [6] IF 5 is a non-explosive, easy-to-handle, industrially available fluorinating agent having a boiling point of 100.5 ° C. and a melting point of 9.4 ° C. Fluorination by IF 5 is used only in the process of adding IF to perfluoroolefins and substituting iodine for perfluoroolefins for fluorine (M. Sakai, Organic Fluorine Chemistry I, 1970, pp348-351, GIHODO SHUPPAN Co., Ltd .: AA Banks, HJ Haszeldine, and V. Kerrigan, J. Chem. Soc., 1948, 2188 .: RD Chambers, WKR Musgrave, and J. Savory, J. Chem. Soc., 1961, 3779 .). However, since IF 5 is difficult to control high oxidative property, its use as a fluorinating agent for organic compounds having hydroxy groups, carbonyl groups and the like has not been known until now.
