Benzylfluorocarbene: Reactions and kinetics

Benzylfluorocarbene, generated from the corresponding diazirine, is accompanied by considerable azine formation. Its rearrangement to β-fluorostyrene isomers in tetrachloroethane is characterized by E(a) = 3.2 kcal/mol and log A = 9.5 s-1.

REACTIVE INTERMEDIATES IN THE PHOTOLYSIS AND THERMOLYSIS OF 3-CHLORO-3-BENZYLDIAZIRINE

The photochemical and thermal decomposition of 3-chloro-3-benzyldiazirine have been studied in different reaction conditions.The decomposition gives rise to benzylchlorocarbene which can rearrange to E and Z chlorostyrene and/or react with the environment.In the presence of acetic acid the main product is 1-chloro-2-phenylethyl acetate.Experiments with acetic acid-d4 showed that some of the chlorostyrene is formed from the carbocation; other experiments conducted with tetramethylethylene as a carbene trapping agent show that the carbene is formed even in the presence of acetic acid.
