The synthesis of chalcogenated pyrazole-fused isocoumarins and ninhydrin-based hydrazones was accomplished using the same starting materials by changing the solvent and temperature of the reactions.
A highly effective method for synthesizing N-arylhydrazones by means of light-promoted C–N coupling of (hetero)aryl halides with benzophenone hydrazone with catalysis by a Ni(II)–aryl halide complex was reported.
Synthesis of five novel copper–arylhydrazone complexes and their catalytic activity for microwave-assisted click reaction in water and glycerol.
This review systematically summarizes recent advances in azide-free synthetic methodologies for 1,2,3-triazole construction, with a focus on alternative nitrogen sources including hydrazones, diazo compounds, and nitrite esters/salts.
No trend was detected between the linker length and catalytic activity of bridged copper(II)-arylhydrazone complexes in cyanosilylation of benzaldehyde with trimethylsilyl cyanide.
