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
, p. 17271 - 17277 (2019/01/03)
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.
The photochemistry of various para-substituted tetrafluorophenyl azides in acidic media and the formation of nitrenium ions
Michalak, Jacek,Zhai, Hong Bin,Platz, Matthew S.
, p. 14028 - 14036 (2007/10/03)
Laser flash photolysis of polyfluorinated aryl azides in acetonitrile at ambient temperature produces singlet nitrenes which have lifetimes of tens to hundreds of nanoseconds. The lifetimes are controlled by ring expansion and intersystem crossing to the
Photochemistry of Phenyl Azide: The Role of Singlet and Triplet Phenylnitrene as Transient Intermediates
Leyva, Elisa,Platz, Matthew S.,Persy, Gabriele,Wirz, Jakob
, p. 3783 - 3790 (2007/10/02)
The sequence of transient intermediates formed by the photolysis of phenyl azide (1) was determined by a combination of techniques including absorption, emission, and EPR spectroscopies as well as quantitative product analyses of irradiated glassy solutio
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.
