Polymer-anchored peroxo compounds of molybdenum and tungsten as efficient and versatile catalysts for mild oxidative bromination was written by Boruah, Jeena Jyoti;Das, Siva Prasad;Borah, Rupam;Gogoi, Sandhya Rani;Islam, Nashreen S.. And the article was included in Polyhedron in 2013.COA of Formula: C6H6BrNO This article mentions the following:
A polymer supported peroxomolybdate(VI) compound [MoO2(O2)(CN)2]-PAN [PAN = poly(acrylonitrile)] (PANMo) was obtained by reacting H2MoO4 with 30% H2O2 and the macromol. ligand, PAN at near neutral pH. The macrocomplex was characterized by elemental anal. (CHN and EDX anal.), spectral (IR, UV-visible and 13C NMR, 95Mo NMR), thermal (TGA-DTG) as well as SEM studies. The catalytic activity of PANMo and its previously reported tungsten containing analog PANW, in oxidative bromination of organic substrates was explored. The supported complexes could serve as efficient heterogeneous catalysts for the oxidative bromination of a variety of structurally diverse aromatic compounds, with H2O2 as terminal oxidant, to afford bromo organics in impressive yields under environmentally clean conditions. The catalysts afforded regeneration and could be reused for a min. of six reaction cycles. In the experiment, the researchers used many compounds, for example, 4-Amino-3-bromophenol (cas: 74440-80-5COA of Formula: C6H6BrNO).
4-Amino-3-bromophenol (cas: 74440-80-5) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.COA of Formula: C6H6BrNO
