Abstract: 
Carbenesand nitrenes are key intermediates involved in numerouschemical processes, and they have attracted considerable attentionin synthetic chemistry, biochemistry, and materials science. Eventhough parent arsinidene (H-As) has been characterized well, the highreactivity of subsituted arsinidenes has prohibited their isolationand characterization to date. Here, we report the preparation of tripletphenylarsinidene through the photolysis of phenylarsenic diazide isolatedin an argon matrix and its subsequent characterization by infraredand UV/vis spectroscopy. Doping matrices containing phenylarsinidenewith molecular oxygen leads to the formation of hitherto unknown anti-dioxyphenylarsine.The latter undergoes isomerization to novel dioxophenylarsine upon465 nm irradiation. The assignments were validated by isotope-labelingexperiments and agree very well with B3LYP/def2-TZVP computations.
