Diazinium salts with dihydroxyacetophenone skeleton: Syntheses and antimicrobial activity.

Herein we report a feasible study concerning syntheses, structure and antimicrobial activity of some new diazinium salts with dihydroxyacetophenone skeleton. A fast, general, environmentally friendly, and facile method for preparation of diazinium salts under microwave and ultrasounds irradiation is presented. Antimicrobial tests prove that some diazine compounds have a remarkable activity against different microorganisms (germs and fungi), the pyrimidine derivatives being more active.
