Preparation method of organic lanthanum precursor La (iPr2-FMD)3

The invention discloses a preparation method of an organic lanthanum precursor La (iPr2-FMD) 3, La (iPr2-FMD)3 is prepared through reaction of N, N'-diisopropylformamidine, ML and LaCl3.xTHF, ML is metal hydride or amino metal, M is metal sodium or potassium, L is H, NH2 or N(SiMe3)2, and the value of x in LaCl3.xTHF is 0.7-1.5. According to the invention, the N, N'-diisopropyl formamidine sodium salt or potassium salt can react with LaCl3.xTHF to prepare La(iPr2-FMD) 3, and during sublimation purification, as the vapor pressure of the N, N'-diisopropyl formamidine sodium salt or potassium salt is lower than that of a lithium salt, the N, N'-diisopropyl formamidine sodium salt or potassium salt can be easily separated from the product La (iPr2-FMD)3, the purity of the product is improved, and the yield is higher than that when the lithium salt is used.
