| Abstract: | An eco‐friendly and cheap Zn‐H2O‐CO2 system was presented for chemoselective reduction of nitrobenzenes to anilines with high yields (80% –97% isolated yields) in supercritical carbon dioxide. This process brings together the very important green chemistry technologies–the use of carbon dioxide as a solvent and the use of water as a hydrogen donor. |
