Spectroscopic Identification of the Phenyltelluryl Radical and its Reactivity Toward Molecular Oxygen

Abstract

The phenyltelluryl radical was prepared by high-vacuum flash pyrolysis of diphenyl ditelluride and was chacracterized by matrix isolation IR and UV/vis spectroscopy. After doping the matrix with molecular oxygen and allowing bimolecular reactions the hitherto unkown phenyltelluro peroxy radical formed and was identified via IR spectroscopy. Irradiation with light at λ = 436 nm leads to isomerization to the thermodynamically more stable novel phenyl telluroyl radical. All experimental findings agree well with DFT computations (B3LYP/Def2QZVPP).
