Elimination reactions often compete with substitution reactions. In this reaction, a substrate (typically an alkyl halide) eliminates one equivalent (unit) of acid to form an alkene. Two possible mechanisms are available for this elimination reaction – E1 and E2 mechanisms.

WebJan 8, 2024 · The proposed reaction mechanism follows a novel route of 1,3 dipole generation via copper-carbene intermediate Int-27 formation from ynamide 1e which further transforms into 1,3-dipole intermediate Int-38. The 1,3-dipole intermediate Int-28 undergoes formal [3 + 2] cycloaddition with the alkene reaction partner 29 in the last step. http://api.3m.com/dehydrohalogenation+of+2+bromobutane
