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
苯基碲烷基通过二苯基二碲化物的高真空快速热解法制备,并通过基质分离IR和UV / Vis光谱法进行表征。用分子氧掺杂基质并进行双分子反应后,形成了迄今未知的苯基碲过氧自由基,并通过红外光谱进行了鉴定。用λ= 436 nm的光照射会导致异构化为热力学更稳定的新型苯基碲酰酰基。所有实验结果均与密度泛函理论(UB3LYP / Def2QZVPP和UM06-2X / Def2QZVPP)计算非常吻合。
