Abstract


It is established that the main formation pathways of molecular and fragment ions of a series of novel imidazo[1,5-a]quinoxalin-4-one derivatives upon electron ionization involve elimination of neutral СО, ArCN, and PhCN molecules while upon matrix-assisted laser desorption and electrospray ionization fragment iones are formed only through the elimination of ArCN.
