Abstract

The spectra of ten furan carhoxylic acids are reported and discussed, observing in each case small peak.s (M-28)+ due to CO elimination from the molecular ion. The formation of these ions is due to a migration mechanism of hydroxyl radical, with simulaaneous cleavage of the C-C bond a to the carbonyl group. This process is demonstrated by the appearance of metastable peaks and of doubly charged ions, as well as by the exchange of the acidic H by D. Similar mechanisms are observed for sorne furanic ketones. Mechanisms of fragmentation are given on the basis of comparison of the mass spectra of the studied compounds.
