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.
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 کاملA novel transition metal free [bis-(trifluoroacetoxy)iodo]benzene (PIFA) mediated oxidative ipso nitration of organoboronic acids.
A mild, convenient and transition metal free methodology for oxidative ipso nitration of diversely functionalized organoboronic acids, including heteroaryl- and alkylboronic acids, has been developed at ambient temperature using a combination of [bis-(trifluoroacetoxy)]iodobenzene (PIFA) - N-bromosuccinimide (NBS) and sodium nitrite as the nitro source. It is anticipated that the reaction proce...
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...
متن کاملNitration of naphthalene and remarks on the mechanism of electrophilic aromatic nitration.
Naphthalene was nitrated with a variety of nitrating agents. Comparison of data with Perrin's electrochemical nitration [Perrin, C. L. (1977) J. Am. Chem. Soc. 99, 5516-5518] shows that nitration of naphthalene gives an alpha-nitronaphthalene to beta-nitronaphthalene ratio that varies between 9 and 29 and is thus not constant. Perrin's data, therefore, are considered to be inconclusive evidence...
