Abstract
Mass fragmentation of 4-iminopentan-2-one N-substituted with organosilicon group suggests that in the gas phase upon electron ionization (EI) conditio ns only 4-imino-2-keto tautomer occurs. The simultaneous occurrence of 4-am inopent-3-en-2-keto tautomeric form was ruled out on the basis of mass frag mentation of some alkylaromatic derivatives of 4-aminopent-3-en-2-one.
