Abstract An efficient and safe method for nitration of aromatic compounds and decarboxylative nitration of α,β-unsaturated acids was developed using trichloroisocyanuric acid (TCICA)/dimethylformamide (DMF) in the presence of NaNO2. The reaction times of conventional protocol reduced from 8–10 h to 1.0–1.5 h (60–90 min) under sonication, even though the yields are comparable under both the conditions

Zeolite Y was found to be an efficient catalyst for a facile nitration of aromaticcompounds with acetonitrile as the solvent in the presence of small amounts of HNO3 at room temperature. The reactions afforded mono-nitro derivatives of aromaticcompounds in about three hours under stirred conditions with high yields and regioselectivity. The reaction times drastically reduced to about 20 min under
A study of the double bond reactivity in Δ3-cyclohexene derivatives with one polar substituent in the side chain and Me substituents in the ring has shown that the preferred conformation for these compounds, indepenent of their stereochemistry, has the polar group axial, giving rise to supra-annular interaction. Such interaction decreases the nucleophilicity of the ring double bond. A similar study
