Ferrocene-containing tetrahydropyrazolopyrazolones: Antioxidant and antimicrobial activity
(Journal of Inorganic Biochemistry, 2018-12)
A series of ferrocenes which contain dinitrogen-fused pyrazolidinone ring were synthesized from acryloylferrocene (4) and N,N′‑cyclic azomethine imines (3). Novel 5‑aryl‑6‑ferrocenoyltetrahydropyrazolo[1,2‑a]pyrazol‑1(5H)-ones ...
Synthesis, structural and electrochemical characterization of novel 1,3-ketoureas bearing a ferrocenyl group
(Polyhedron, 2018-02)
Twenty-two novel 1,3-ketourea derivatives bearing ferrocene moiety were synthesized in good-to-excellent yields (up to 99%) via simple and efficient protocol. This solvent- and catalyst-free synthesis was achieved by ...
