The present application relates to the technical field of inorganic synthesis, and provides a preparation method of cis-diiododiammine
platinum (II). The present application dissolves
potassium chloroplatinite in a polar
solvent to obtain a
potassium chloroplatinite solution;
iodine source and
nitrogen source are sequentially added into the
potassium chloroplatinite solution to react, so as to obtain the cis-diiododiammine
platinum (II). The present application uses potassium chloroplatinite,
iodine source and
nitrogen source as raw materials, can promote the efficient reaction under mild conditions, and improves the reaction efficiency and product yield. The results of examples show that the reaction time is only 0.5 h when the cis-diiododiammine
platinum (II) is prepared by the method of the present application, and the product yield can reach more than 95%. In addition, the process of the present application is simple, the synthesis
route is short, the safety is good, the raw materials are cheap and easy to obtain, and the present application is suitable for industrial
batch production.
