Phenylnitrene anion radical (PhN-.) was prepared in a flowing afterglow apparatus by dissociative electron attachement of phenyl azide (PhN3).PhN-. undergoes a very slow reaction with PhN3, producing PhN4Ph-. and PhN2Ph-. in a ratio of 4:1.The proton affinity pf PhN-. was bracketed from kinetic studies with various potential proton donors, PA(PhN-.) = 372 +/- 2 kcal mol-1, from which ΔHf0(PhN-.) = 60 +/- 2 kcal mol -1 was calculated.With alcohols which are too weakly acidic to directly protonate PhN-.
