The outer complex initially formed on electrophilic addition has been shown to have the structure 1 in the prototypical reaction of ethene with BrCl. The rotational spectra of two isotopomers of a weakly bound complex were observed by Fourier transform microwave spectroscopy with a fast‐mixing nozzle. This result is important for the understanding of the mechanism of electrophilic addition, a fundamental reaction in organic chemistry.
