Bromine-olefin charge transfer complexes as essential intermediates in bromination

3 Bromine-olefin charge transfer complexes as essential intermediates in bromination 

In agreement with Dewar s proposal (Dewar and Leplay, 1961) and by analogy with the long-established halogen-aromatic molecular complexes 

Subsequently, and although no experimental proof was accessible, it was commonly agreed that CTCs are active intermediates in bromination. In particular, Olah et al. (1974a) concluded from nmr spectra that the bromine- 

Some years later, Kochi et al (Fukuzumi and Kochi, 1981) applied their theory on electron and charge transfers to electrophilic alkene bromination (Kochi, 1988) by comparing the reactivities of various alkenes in bromination and in mercuration. Although the substituent effect trends in the two reactions are totally different, a linear relationship (7) is observed when the reactivities 

Although the involvement of molecular bromine-olefin complexes as active intermediates in bromination had been widely assumed, this was demonstrated
