Article abstract of DOI:10.1016/S0040-4020(01)97448-4

The mass spectra of deuterium and ¹⁸O labeled 3-(m-nitrobenzoyl)-2-methylpropanoic acid reveal that the McLafferty rearrangement and the rearrangement process leading to protonated m-nitrobenzoic acid do not take place via a common intermediate. H-D exchange phenomena point to a stepwise McLafferty rearrangement.
