corresponding 1 -(a-phenylalkyl)- 1,4-dihydrobenzoic acids 4 and 5. The major secondary fragmentation is loss of benzene from 1 and 2. It is shown by deuterium labeling that 1 and 2 ions undergo repeated ring-to-ring proton transferreactions, equilibrating all of the 11 "aromatic" hydrogenatoms within s without involving those from the aliphatic chain. A competition between the ring-to-ring (quasi-intermolecular)
