Mild and highly efficient I2 and Et3N aided cyclodeselenization of in situ generated selenosemicarbazide is described to obtain 2-amino-1,3,4-oxadiazole peptidomimetics.
A novel catalytic system consisting of I2-SDS-H2O has been developed which cleaves 2,3-diaza-1,3-butadiene, 1-aza-1,3-butadienes, oximes and in presence of indoles in the medium uses the corresponding aldehyde products to produce bis(indolyl)alkanes in situ. This one pot simple and mild dual catalytic system works in water at room temperature under neutral conditions.
A novel heterogeneous Co3O4/Co(OH)2 hybrid is prepared using a controllable facile one-pot hydrothermal reaction. The as-obtained hierarchical Co3O4/Co(OH)2 hybrids can serve as highly efficient electrocatalytic water oxidation catalysts for alkaline electrolytes.
<p>The rapid and environmental synthetic route to produce 1<em>H</em>-indazolo[1,2-b] phthalazine-1,6,11-triones and 1<em>H</em>-pyrazolo[1,2-b]phthalazine-5,10-diones derivatives have been developed <em>via</em> multicomponent and one-pot reactions of various aldehydes, cyclic or acyclic 1,3-diketones with: <em>i)</em> phthalhydrazide or <em>ii)</em> phthalic anhydride-hydrazinium hydroxide using wet 2,4,6-trichlorotriazine (TCT) as catalyst under solvent-free conditions. Simple and mild reaction conditions, the use of a cheap catalyst and easy workup and isolation are notable features of this method.</p>
