  • Mechanism of electron impact ionization-induced halogen elimination from 2-methyl-2-bromosuccinates
    作者:D. Bornstein、A. Mandelbaum、I. Vidavsky、B. Domon、D. R. Mueller、W. J. Richter

    AbstractThe electron impact‐induced halogen elimination from 2‐methyl‐2‐bromosuccinates occurs only in the one of the two isomeric methyl ethyl esters in which the ethoxycarbonyl group is remote from the halogen, in analogy with the corresponding previously reported halosuccinates. However, the occurrence of debromination in dimethyl 2‐methyl‐2‐bromosuccinate contrasts with the behaviour of dimethyl bromosuccinate, indicating different mechanisms for this process in the two systems. Collision‐induced dissociation (CID) and deuterium labelling studies led to the conclusion that a hydrogen transfer from the 2‐methyl group to a carbonyl precedes the elimination of Br˙ from dimethyl 2‐methyl‐2‐bromosuccinate, resulting in a protonated dimethyl itaconate structure for the [M – Br]+ ion. An analogous process is the major route leading to [M – Br]+ ion from 1‐methyl‐4‐ethyl 2‐methyl‐2‐bromosuccinate. In this case deuterium labelling and CID measurements indicated a significant contribution of methyl ethyl citraconate and possibly mesaconate owing to partial operation of a mechanism similar to that reported for 1‐methyl‐4‐ethyl 2‐bromosuccinate.
