title: Laser flash photolysis study of carboethoxynitrene.
abstract: [reaction: see text] Laser flash photolysis (LFP, 266 nm) of carboethoxyazide produces a mixture of the ethoxycarbonyl radical (lambda(max) = 333 nm, tau = 0.4 micros, CF(2)ClCFCl(2), ambient temperature) and triplet carboethoxynitrene (lambda(max) = 400 nm, tau = 1.5 micros, CF(2)ClCFCl(2), ambient temperature). The carbon-centered radical is selectively scavenged by oxygen allowing sole observation of the triplet nitrene. We deduce that the singlet nitrene has a lifetime between 2 and 10 ns in CF(2)ClCFCl(2) at ambient temperature.
