Synthesis and Reactivity of 3‐Aminosydnones in Cycloaddition Reactions With Alkynes

Chemistry – A European Journal, EarlyView.
The synthesis, functionalization, and reactivity as dipoles of 3‐aminosydnones have been investigated. These neglected compounds undergo smooth cycloaddition reactions with strained alkynes, leading to 1‐aminopyrazoles. ABSTRACT We present in this article the synthesis, functionalization, and properties of 3‐aminosydnones, a forgotten class of ...

S‐Doped Carbon Nitride Thin Films From a Triazole Precursor

Carbon Innovation, EarlyView.
Sulfur‐functionalized carbon nitride thin films are synthesized via low‐temperature chemical vapor deposition using a triazole‐derived precursor. Tunable sulfur incorporation modulates electronic and optical properties and enables efficient visible‐light photocatalysis with high conversion and selectivity.
