Electrospray ionization mass spectrometric fragmentation of hydroquinone derivatives

The fragmentation patterns of nine di‐, tri‐ and tetracyclic hydroquinones with potential antitumor activity were rationalized by invoking competing mechanisms that included sterically accelerated homolytic cleavage, Meerwein‐type rearrangements and dehydrations through elimination or intramolecular...

Description
Summary:The fragmentation patterns of nine di‐, tri‐ and tetracyclic hydroquinones with potential antitumor activity were rationalized by invoking competing mechanisms that included sterically accelerated homolytic cleavage, Meerwein‐type rearrangements and dehydrations through elimination or intramolecular nucleophilic substitution.
