Urazolyl radicals are a class of persistent nitrogen-centered radicals. In previous work, we successfully formed self-assembled monolayers substituted urazolyl on gold surfaces. To extend the scope these investigations, sought to form monolayer using radical species that knew existed predominantly in dimerized N-N instead existing as free N-centered species, had previously been investigated. We...

   One-pot reaction of aldehydes with thiosemicarbazide was performed using NaBH4 and Fe3O4 magnetic nanoparticles (MNPs). The reaction mixture of thiosemicarbazide and carbonyl compounds was stirred under reflux condition in the present of Fe3O4 MNPs and NaBH4.The optimum amount of Fe3O4</su...

Appropriately substituted N-centered urazolyl radicals are capable of generating interesting cage-like structures upon forming N-N bonds. The generated by the oxidation corresponding NH urazole precursors. We synthesized a triurazole precursor that we hoped would dimerize through formation three bonds to afford large molecular cage. Unfortunately, attempts at urazoles form instead only lead ran...

abstract: in a wide search program towards new and efficient antimicrobial agents, a series of 4-substituted-1,2,4-triazolidine-3,5-dione derivatives namely urazoles holding an alkyl moiety at position 4 have been synthesized and tested for their in vitro antibacterial and antifungal activities. the structures of these compounds have been investigated by spectral data. the synthesized compounds...
