To date, in mass spectral studies of esters, a single reference to loss of water from the molecular ions has been noted. A series of aromatic esters which exhibit that sparsely observed phenomenon are reported herein. Through a combination of synthetic and deuterium labeling studies, support for a unique fragmentation route for the loss of water from these ester molecular ions has been obtained.
