Bromination of cinnamyl halides, and related studies

, 1982
The rates of bromination of the (E)-cinnamyl halides in acetic acid have been measured so that the electronic effects of a halomethylene group on a π system might be better understood. The relative rates of bromination decrease in the order PhCH=CHCH2F >

Remote Migratory Reductive Arylation of Unactivated Alkenes Enabled by Electrochemical Nickel Catalysis

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
we have developed an electrochemical Ni−H catalyzed arylation coupling method of unactivated alkenes with aryl halides. The method displays broad functional group tolerance and proceeds under very mild conditions. Furthermore, aryl chlorides were also compatible substrates in this catalytic system. This conversion holds significant implications for the

Bromination of endo- and exo-benzocyclobutenonorbornene derivatives: neighbour group effect on bromination

, 2005
The electrophilic addition of bromine to 13-anti-bromo-endo-benzocyclobutenonorbornene 7 at-50 +/- 5 degrees C has led in high yield to the formation of the rearranged dibromides 9, 10 and 11.
