Conclusions
-
1.
The relative rate constants for the addition of fluorobromocarbene to a number of arylethylenes were determined.
-
2.
The reaction proceeds by the electrophilic addition mechanism via a weakly polar transition state.
-
3.
In the arylethylene series the selectivity of fluorobromocarbene is close to that of the dichloro- and difluorocarbenes.
