Title: New fluorine-containing oligomer and its production
Inventor: ONO TAIZO
IPC: C07C209/68
Filed: 1994-07-29
Abstract: PURPOSE:To produce a new compound useful as an intermediate for synthesis of a surfactant, a dye, an agrochemical or a medicine. CONSTITUTION:This new compound is expressed by formula I or II (R<1> is R<2> are each a 1 to 5C perfluoroalkyl or bonded through O or N to form a five- to seven-membered heter6cycle), e.g. perfluoro[1,3-bis(pyrrolidino)2-butene]. This compound of formula I is produced by conducting oligomerization reaction of a perfluorovinylamine of formula III in the presence of a fluoride ion catalyst in a polar solvent (e.g. DMF) at 0 to 200 deg.C. The compound of formula II is produced by isomerizing the compound of formula I in the presence of a fluoride ion in a polar solvent. Heat resistance, chemical resistance, light resistance and low surface characteristics which are the properties essential to the perfluoroalkyl group can be utilized. These compounds are directly fluorized and the resultant saturated compounds are useful as a substitute CFC, a fluorosolvent or a heating medium in the fields of cooling medium, foaming agent, detergent, etc. Further, these compounds can be emulsified and the resultant emulsion is useful also as a medical agent, e.g. a contrast medium for <19>F-NMR.
