In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Detailed Optimization of Polycondensation Reaction via Direct C-H Arylation of Ethylenedioxythiophene, published in 2013, which mentions a compound: 172418-32-5, mainly applied to ethylenedioxythiophene polycondensation palladium carboxylic acid catalyst, Related Products of 172418-32-5.
The polycondensation reaction of 3,4-ethylenedioxythiophene with 2,7-dibromo-9,9-dioctylfluorene via Pd-catalyzed direct arylation gives poly[(3,4-ethylenedioxythiophene-2,5-diyl)-(9,9-dioctylfluorene-2,7-diyl)]. The reaction conditions are optimized in terms of the Pd precatalysts, reaction time, and carboxylic acid additives. The combination of 1 mol% Pd(OAc)2 and 1-adamantanecarboxylic acid as an additive is the optimized catalytic system, and it yields the corresponding polymer with a mol. weight of 39,400 in 89% yield. The polycondensation reaction, followed by an end-capping reaction, effectively provides a linear polymer without Br terminals.
《Detailed Optimization of Polycondensation Reaction via Direct C-H Arylation of Ethylenedioxythiophene》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(trans-Di-μ-acetatobis[2-[bis(2-methylphenyl)phosphino]benzyl]dipalladium)Related Products of 172418-32-5.
