🧪 **From Azide to Amine in One Step! ⚡**

The **Staudinger Reaction** is one of the most elegant transformations in organic chemistry. It converts **organic azides (R–N₃)** into **primary amines (R–NH₂)** using a phosphine (PR₃) followed by hydrolysis.

🔹 Mild reaction conditions
🔹 High chemoselectivity
🔹 Excellent functional group tolerance
🔹 Widely used in medicinal chemistry, peptide synthesis, and bioorthogonal chemistry
