The invention discloses a synthetic method of a fluorine-containing secondary amine compound. Pentamethylcyclopentadienyl iridium chloride dimer is used as a metal catalyst, fluoroalkyl comes from fluorinated alcohol, alkali is used as a co-catalyst, and the fluorine-containing secondary amine is prepared via the following step: primary amine reacts with the fluorinated alcohol under the action of the transition metal iridium catalyst and the alkali in an organic solvent to obtain the fluorine-containing secondary amine compound. The method overcomes the defects in the prior art that the fluorine-containing alkylating agent is high in toxicity and instable and needs to be prepared in advance, the reaction operation is complex, the steps are fussy and the like, and can obtain considerable yield. The adopted fluorinated alcohol is readily available, stable in chemical property and low in toxicity. The method is simple in reaction, has very high atom economy and step economy, and is energy-saving, environment-friendly and simple in operation. By adopting [Cp*IrCl2]2 as the catalyst, ligands are not needed, and the system is easy to realize.
