Solvent-Drop Grinding Method Efficient Synthesis DPPH
· Abstract Highly efficient one-pot solvent-free grinding method was reported for synthesis of chalcones 3a-j 5a b 7 and bis-chalcones 9 11. Cyclodehydration of bis-chalcones 9 11 and chalcones 3 with hydrazine derivatives under solvent- free grinding method afforded bis-pyrazolines 12a b 13a b and pyrazoline derivatives 14a-g respectively.
