A novel thiophene derivative, namely 2,5-diisopropenylthiophene (DIT) was synthesized by Suzuki-Miyaura cross-coupling reaction (SMCCR). The influence of reaction parameters, such as temperature, solvent, stoichiometry of reagents, role of the base and reaction medium were thoroughly discussed in view of yield optimization and environmental impact minimization. Basic design of experiment (DoE) and multiple linear regression (MLR) modeling methods were used to interpret the obtained results. DIT was employed as a comonomer in the copolymerization with waste elemental sulfur through a green process, inverse vulcanization (IV), to obtain sulfur-rich polymers named inverse vulcanized polymers (IVPs) possessing high refractive index (n 1̃.8). The DIT comonomer was purposely designed to (i) favor the IV process owing to the high reactivity of the isopropenyl functionalities and (ii) enhance the refractive index of the ensuing IVPs owing to the presence of the sulfur atom itself and to the high electronic polarizability of the π-conjugated thiophene ring. A series of random sulfur-r-diisopropenylthiophene (S-r-DIT) copolymers with sulfur content from 50-90 weight% were synthesized by varying the S/DIT feed ratio. Spectroscopic, thermal and optical characterizations of the new IVPs were carried out to assess their main chem.-phys. features. In addition to this study using 2,5-Dibromothiophene, there are many other studies that have used 2,5-Dibromothiophene(cas: 3141-27-3Application of 3141-27-3) was used in this study.
2,5-Dibromothiophene(cas: 3141-27-3) , is mainly used as pharmaceutical intermediate and synthesis intermediate. 2,5-Dibromothiophene may be used in the preparation of soluble α,ω-diformyl-a-oligothiophenes.Application of 3141-27-3
