Switching the Spin State of Pentafluorophenylnitrene: Isolation of a Singlet Arylnitrene Complex
Mieres-Perez, Joel,Costa, Paolo,Mendez-Vega, Enrique,Crespo-Otero, Rachel,Sander, Wolfram

The chemistry of arylnitrenes is dominated by their triplet ground states and excited open-shell singlet states. This results in radical-type reactions and unwanted rearrangements, which diminish the use of arylnitrenes as intermediates in organic synthes
Photochemistry of fluorinated phenyl nitrenes: Matrix isolation of fluorinated azirines
Morawietz, Jens,Sander, Wolfram
, p. 4351 - 4354 (2007/10/03)
2,6-Difluorophenylnitrene and pentafluorophenylnitrene were generated in solid argon at 10 K by irradiation of the corresponding phenyl azides and characterized by IR and UV spectroscopy. Selective irradiation with λ = 444 nm results in the formation of the corresponding azirines, while ketene imines are not produced. On λ = 366 nm irradiation the azirines rearrange back to the nitrenes. The assignment of the azirines is confirmed by ab-initio calculations.
Pentafluorophenyl Nitrene: a Matrix Isolated Aryl Nitrene that Does Not Undergo Ring Expansion
Dunkin, Ian R.,Thomson, Paul C. P.
, p. 1192 - 1193 (2007/10/02)
Photolysis of pentafluorophenyl azide or pentafluorophenyl isocyanate in low-temperature matrices gives pentaflurophenyl nitrene which, in the presence of CO, may react photochemically but not thermally to give the isocyanate.
