Lanthanide-EDTA complexes covalently bonded on Fe3O4@SiO2 magnetic nanoparticles promote the green, stereoselective synthesis of: N-Acylhydrazones
In the last few years, many synthetic methods have been developed using magnetic nanomaterial-based catalysts with considerable advantages for the efficiency, selectivity and applicability of green procedures. In this work, lanthanide-EDTA complexes coval

Stereoselective, solvent free, highly efficient synthesis of aldo- and keto-: N -acylhydrazones applying grindstone chemistry
A mild and efficient synthesis of N-acylhydrazones has been developed, applying a simple grindstone procedure, leading to a library of 51 examples exhibiting a broad variety of structural features, 21 of them described for the first time in this paper. Th

Mild, Stereoselective, and Highly Efficient Synthesis of N-Acylhydrazones Mediated by CeCl3·7H2O in a Broad Range of Solvents
In a mild and practical approach, hydrazides and aldehydes underwent condensation reactions that were mediated by cerium(III) chloride to be rapidly converted into N-acylhydrazones. This method uses a minimal catalytic amount of cerium(III), is stereosele
