Electron impact-induced fragmentations of 2-substituted 5,5-bis(carboethoxy)l,3-dioxanes were studied by exact mass measurements and metastable ion analysis. The substituent R on C(2) of the heterocyclic ring has little influence on the principal cleavage reactions. Elimination of CH,O/CO and C,H,O/
