《Synthesis and characterization of novel soluble poly(arylene ether amide triphenylphosphine oxide)s by heterogeneous palladium-catalyzed carbonylation polymerization》 was written by Li, Jianying; Huang, Bin; Tang, Huali; Cai, Mingzhong. Reference of 3-Iodophenol And the article was included in Journal of Macromolecular Science, Part A: Pure and Applied Chemistry in 2020. The article conveys some information:
A new aromatic diiodide monomer, bis(4-(3-iodophenoxy)phenyl)phenylphosphine oxide (BIPPO), was prepared by condensation of bis(4-fluorophenyl)phenylphosphine oxide with 3-iodophenol. A series of poly(arylene ether amide triphenylphosphine oxide)s were synthesized via heterogeneous palladium-catalyzed carbonylative polycondensation of BIPPO, aromatic diamines, and carbon monoxide. Polymerization reaction proceeded smoothly in N,N-dimethylacetamide (DMAc) at 120°C with 1,8-diazabicyclo[5,4,0]-7-undecene (DBU) as the base by using the bidentate phosphino-modified magnetic nanoparticles-anchored palladium complex [2P-Fe3O4@SiO2-PdCl2] as a recyclable catalyst under 1 bar of CO, producing new poly(arylene ether amide triphenylphosphine oxide)s with inherent viscosities ranging from 0.69 to 0.76 dL/g. All the polymers obtained were easily soluble in strong polar aprotic organic solvents and even in less polar pyridine at room temperature, and provided transparent, flexible and tough films by casting from their DMAc solutions These polymers displayed good thermal stability with the glass transition temperatures ranging from 196 to 249°C, the temperatures at 5% weight loss ranging from 441 to 490°C in nitrogen. All the polymers were amorphous and their films showed good mech. behavior with tensile strengths of 78.5-91.6 MPa, tensile moduli of 2.15-2.69 GPa, and elongations at break of 9.8-14.6%. In addition to this study using 3-Iodophenol, there are many other studies that have used 3-Iodophenol(cas: 626-02-8Reference of 3-Iodophenol) was used in this study.
3-Iodophenol(cas: 626-02-8) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.Reference of 3-IodophenolHalogenation of aromatic hydrocarbons is a very important reaction via an electrophilic aromatic substitution.
