The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Tricyclohexylphosphonium tetrafluoroborate(SMILESS: F[B-](F)(F)F.[PH+](C1CCCCC1)(C2CCCCC2)C3CCCCC3,cas:58656-04-5) is researched.Product Details of 3229-00-3. The article 《Synthesis of poly(5,6-difluoro-2,1,3-benzothiadiazole-alt-9,9-dioctylfluorene) via direct arylation polycondensation》 in relation to this compound, is published in Journal of Polymer Science, Part A: Polymer Chemistry. Let’s take a look at the latest research on this compound (cas:58656-04-5).
Poly(5,6-difluoro-2,1,3-benzothiadiazole-alt-9,9-dioctylfluorene) was successfully synthesized via direct arylation polycondensation of 5,6-difluoro-2,1,3-benzothiadiazole and 2,7-dibromo-9,9-dioctylfluorene. The reaction conditions were optimized, and a polymer with number-average mol. weight (Mn) of 41,000 was obtained by using Pd(OAc)2, PtBu2Me-HBF4, pivalic acid, K2CO3, and toluene as catalyst, ligand, additive, base, and solvent, resp. The polycondensation was also performed with 5,6-dioctyloxy-2,1,3-benzothiadiazole or 2,1,3-benzothiadiazole as the comonomer, and the results indicate that the introduction of electron-withdrawing fluorine atoms at the ortho-positions to the C-H bonds is essential for the reactivity of the direct arylation.
Different reactions of this compound(Tricyclohexylphosphonium tetrafluoroborate)Name: Tricyclohexylphosphonium tetrafluoroborate require different conditions, so the reaction conditions are very important.
