Photoinduced Reactivity of the Soft Hydrotris(6-tert-butyl-3-thiopyridazinyl)borate Scorpionate Ligand in Sodium, Potassium, and Thallium Salts

found to exhibit pronounced photoreactivity. Full elucidation of this
process revealed the formation of 6-tert-butylpyridazine-3-thione
(PnH) and 4,5-dihydro-6-tert-butylpyridazine-3-thione
(H2PnH). Under exclusion
of light, no solvolytic reactions occur, allowing the development
of high-yield preparation protocols for the sodium, potassium, and
thallium salts and improving the yield for their derived copper boratrane
complex. The photoreactivity is relevant for all future studies with
electron-deficient scorpionate ligands.
