A new method for the Synthesis of 3-(3-methoxy-2-nitro-3-phenylpropyl)-9H-carbazole viaFriedel-Crafts reaction through nitroolefins derivatives. This the first type Friedel-Crafts reaction of the nitroolefin derived from Bayliss-Hillman mediated by con. H2SO4 thus giving a simple synthesis of substituted olefin derivatives. Although various electron deficient alkenes such as α,β-unsaturated carbonyl compounds, nitriles, sulfones and phosphonates have been employed as substrates in the
