Abstract
A new method for the synthesis of complexes PtIV(NHC)X4L (NHC is N-heterocyclic carbene of imidazole or benzimidazole series; X = Cl, Br; L is N-coordinated pyridine or NHC) based on mechanochemical oxidation of complexes PtII(NHC)X2L with dichloroiodobenzene (PhICl2) or pyridinium hydrobromide perbromide (PyHBr3) was proposed. Mechanochemical activation led to reduction in the synthesis time and increase in the selectivity of halogenation and yields of the target PtIV complexes (74–98%) as compared to the reaction in solutions.
