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 Palladium-Catalyzed Dehydrohalogenative Polycondensation of 2-Bromo-3-hexylthiophene: An Efficient Approach to Head-to-Tail Poly(3-hexylthiophene), published in 2010-08-25, which mentions a compound: 172418-32-5, mainly applied to palladium catalyst dehydrohalogenative polycondensation regioregular polythiophene, COA of Formula: C46H46O4P2Pd2.
Dehydrohalogenative polycondensation of 2-bromo-3-hexylthiophene was successful with Herrmann’s catalyst and tris(2-dimethylaminophenyl)phosphine as catalyst precursors, giving head-to-tail poly(3-hexylthiophene) (HT-P3HT) with high mol. weight (Mn = 30 600, Mw/Mn = 1.60) and high regioregularity (98%) in almost quant. yield (99%).
There is still a lot of research devoted to this compound(SMILES：CC1=C([P]2([Pd+2]3([CH2-]C4=C2C=CC=C4)[O-]/C(C)=O[Pd+2]5([O-]/C(C)=O3)[P](C6=C(C)C=CC=C6)(C7=C([CH2-]5)C=CC=C7)C8=C(C)C=CC=C8)C9=C(C)C=CC=C9)C=CC=C1)COA of Formula: C46H46O4P2Pd2, and with the development of science, more effects of this compound(172418-32-5) can be discovered.
