| General description: | Nitromethane is an aliphatic nitro compound. It undergoes Michael addition reaction with chalcones in the presence of cinchona alkaloid-derived chiral bifunctional thiourea organocatalyst. Its conversion to N2 in the presence of Co-ZSM5 (Zeolite Socony Mobil-5) has been studied. |
