Chromone derived carbazones provide an important antioxidant activity by exhibiting radical scavenging action, Semicarbazones are synthesized in good yield and these act as a good radical scavenger, where the presence of various substituent at C-6 of chromone nucleus tend to alter the activity behaviour, presence of electronegative atom such as fluoro/ chloro enhances the radical scavenging activity in comparison to electron donating group.
