mild reaction conditions and good to excellent yields, providing a feasible method for the preparation of hydrazine derivatives. One of the hydrazine compounds then underwent a one-pot two-step reaction to yield 4,5-dihydropyrazoles. Furthermore, encouraging antifungal activity was demonstrated by the hydrazine and 4,5-dihydropyrazole core structures.
