发明名称 METHOD FOR PRODUCING 2,2-DIFLUOROETHYLAMINE STARTING FROM 2,2-DIFLUORO-1-CHLOROETHANE
摘要 The invention relates to a method for producing 2,2-difluoroethylamine, comprising reacting 2,2-difluoro-1-chloroethane with an imide of formula (II) in the presence of an acid scavenger in order to form a compound of formula (III), wherein in the compounds of formulas (II) and (III), R1 and R2 stand independently of each other for hydrogen or C1-C6 alkyl, or R1 and R2, together with the carbon atoms to which they are bonded, form a six-membered, aromatic ring, which is optionally substituted; and splitting off 2,2-difluoroethylamine by reacting the compound of formula (III) with acid, base, or hydrazine.
