Abstract
The mass spectra of ethyl and isopropyl propionate and butyrate show rearrangement ions R1COOH+ and R1C(OH)2+ formed by reactions [a] and [b]:[Formula: see text]The mass spectra of ethyl-d2 propionate and butyrate show that both [a] and [b] occur with essentially complete scrambling of the alkoxy hydrogens. For the isopropyl esters the mass spectra of the isopropyl-d6 molecules show that reaction [a] occurs by transfer of one of the methyl hydrogens to the acid moiety while reaction [b] occurs predominately by transfer of two methyl hydrogens.
