ipso-Nitration of arylboronic acids with bismuth nitrate and perdisulfate.
An efficient and one pot synthetic method of ipso-nitration of arylboronic acids has been developed. The high efficiency, general applicability, and broader substrate scope including heterocycles and functional groups make this method advantageous. Due to its simplicity, we expect to find application of this method in synthesis.

Nitration of phenol and various 4-substituted phenols with Cu(NO3)2.3H2O, Cu(NO3)2.3H2O/SiO2, 9H2O and Cr(NO3)2. 9H2O in different anhydrous organic solvents are investigated. High selectivity ratio of para vs ortho isomers has been observed. Mono- and dinitro compounds f...
متن کاملPreparation of p-nitrocalix[n]arene methyl ethers via ipso-nitration and crystal structure of tetramethoxytetra-p-nitrocalix[4]areneq
Nitration of p-tert-butylcalix[n]arene methyl ethers under a variety of reaction conditions has been examined. It has been determined that amongst different nitration procedures adopted (AlCl3/KNO3, HNO3/CH3COOH, HNO3/(CH3CO)2O, cerium(IV) ammonium nitrate/CH3COOH), ipso-nitration with CH3COOH/HNO3 gives best yields of p-nitrocalixarenes and work up conditions. ipso-Nitration of tetramethoxytet...
متن کاملMitochondria and regulated tyrosine nitration.
The conditions of the cellular microenvironment in complex multicellular organisms fluctuate, enforcing permanent adaptation of cells at multiple regulatory levels. Covalent post-translational modifications of proteins provide the short-term response tools for cellular adjustment and growing evidence supports the possibility that protein tyrosine nitration is part of this cellular toolkit and n...
