Mechanism of chain photochemical reaction of (n-Bu4N)2[PtCl6] in chloroform

Photochemistry of the (n-Bu4N)(2)[PtCl6] complex in chloroform was studied by means of stationary photolysis and nanosecond laser flash photolysis. The results were explained in the framework of the chain photosolvation. The chain character of photolysis was supported by the quantum yield dependencies on the concentration of the initial complex and light intensity. Spectra of two successive Pt(III) intermediates were registered, their spectral and kinetic characteristics were determined. Based on the obtained experimental data, the literature mechanism of photolysis was revised. (C) 2018 Elsevier B.V. All rights reserved.
