Abstract

The rnass spectra of sorne ,(Ldicarbonilic cornpounds are discussed it was observed that the Me Lafferty rearrangernent constitutes the rnain rnecha­nisrn in /3-diketons and ,6-ketoesters, while malonates breck down according to a-and /Lcleaveges with formation of ionic fragrnents of cyclic structures by rneans of a latter elimination of ethylene. The rnigration of rnethyl radicals with elimination of CO is observed in furfuriliden acetilacetones and migration of ethoxy radicals in keto· esters and rnalonates. The ionic fragrnents (M- l ) found in arornatic compounds, are not observed in furanic analogs. The spectra are reported and mechanisms of fragnientaliou are given.
