Pyrolysis of tetrachlorodiformato complexes of rhenium(III) Re2Cl4(HCOO)2A2, where A = diphenylformamide, dimethylformamide, or pyridine with cis structure and containing a multiple metal-metal bond are studied. Thermal decomposition of these complexes results in low-temperature disproportionation to rhenium(I) pentacarbonylchloride and rhenium(IV) oxide.

Ligand-to-metal charge transfer excitation of organorhenium(VII) oxides R-ReO3 [R = CH3, C2H5, η1-mesityl, C6H5, η5-C5H5, η5-C5H4(CH3), and η5-C5(CH3)5] in acetonitrile or dichloromethane solution leads to photoredox decomposition. It is shown by EPR spectroscopy that radical pairs R?/?ReO3 are generated in the primary step. The overall efficiency is determined by the reactivity of the radicals R?, which decreases in the order CH3 > C2H5 > mesityl > C5H5 > C5H4(CH3) > C5(CH3)5. The regeneration of R-ReO3 is favored with increasing stability of R?. Accordingly the quantum yield varies with R.
