Abstract

Abstract The methane chemical ionization mass spectra of N ‐carbonyldihdrazones of 2,4‐diacetylresorcinol were recorded. The protonated molecular ion was found to be of variable abundance and was often accompanied by [M + 29] + and [M + 41] + ions. Electron impact mass spectra displayed weak molecular ions and were characterized by the scission of a NN bond and subsequent loss of XCONH and XCONHNH 2 .
