《Synthesis and characterization of nitro-functionalized hydroxyl-terminated polybutadiene using N-iodosuccinimide》 was written by Ghayeni, Hamid Reza; Razeghi, Reza; Olyaei, Abolfazl. Product Details of 516-12-1 And the article was included in Polymer Bulletin (Heidelberg, Germany) in 2020. The article conveys some information:
A convenient, inexpensive and highly efficient one-pot procedure of synthesizing nitro-functionalized hydroxyl-terminated polybutadiene (Nitro-HTPB) is reported by the reaction of hydroxyl-terminated polybutadiene (HTPB) and sodium nitrite in the presence of N-iodosuccinimide in EG-EtOAc-H2O at 60°C for 24 h. The investigation of the effective parameters on the synthesis of Nitro-HTPB such as amounts of reactants, temperature and reaction time indicated that in the optimum reaction conditions, the nitration HTPB backbone is restricted to 6.7% of double bonds until the outstanding phys. and chem. properties of HTPB are retained. The Nitro-HTPB was characterized by FTIR, 1H NMR, 13C NMR, DSC and TGA. The polymer showed good thermal stability, yield of 93%, viscosity of 14.2 Pa.s-1, number average mol. weight of 2730 gmol-1 and hydroxyl value of 34 mg KOH per g. After reading the article, we found that the author used 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Product Details of 516-12-1)
1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid. It acts as a source for I+ and involved in Hunsdiecker reactions for the conversion of cinnamic acids, and propiolic acids to the corresponding alfa-halostyrenes and 1-halo-1-alkynes respectively.
