Pyridines and fused pyridines are accessible by a combination of a Lewis acid-catalyzed multicomponent reaction and aromatization involving loss of a 2-furylmethyl chain.
Expression of concern for ‘One-pot synthesis of O-doped BN nanosheets as a capacitive deionization electrode for efficient removal of heavy metal ions from water’ by Ming Ming Chen et al., J. Mater. Chem. A, 2017, 5, 17029–17039.
Monodispersed Ni microspheres with surfaces uniformly covered by Ni dots were constructed through a facile solvothermal synthesis, showing an improved ability to remove Cd2+ ions even at high concentrations in water.
Herein, we demonstrate a hydrothermal route to the one-pot synthesis of polymeric mesoporous silica microcubes (P@MSMCs) for the adsorption of heavy metal ions.
