Bivalent palladium complexes, conjugated aromatic compound and conjugated aromatic hydrocarbon polymer (by machine translation)
The invention provides a bivalent palladium complex having a structure in a formula (I), a formula (II) or a formula (III) and a preparation method of the bivalent palladium complex. The invention also provides a conjugate aromatic hydrocarbon compound having a structure in a formula (IV), a preparation method of the conjugate aromatic hydrocarbon compound, a conjugate aromatic hydrocarbon polymer having a structure in a formula (VI) and a preparation method of the conjugate aromatic hydrocarbon polymer. According to the invention, functional groups, such as C1-C4 alkoxy, cyan, nitryl or an aldehyde group, are introduced into the bivalent palladium complex. The aryl bivalent palladium complex provided by the invention is more stable and insensitive to oxygen and heat and can be used for preparing the conjugate aromatic hydrocarbon polymer by catalyzing AB type aromatic hydrocarbon for coupling polymerization reaction as a catalyst, so that the chain end of the conjugate aromatic hydrocarbon polymer comprises the functional groups; the aryl bivalent palladium complex provided by the invention can be used for synthesizing the conjugate aromatic hydrocarbon compound which comprises the functional groups by being reacted with aromatic hydrocarbon as a reaction substrate.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.40691-33-6, you can also check out more blogs about40691-33-6
