    摘要: The invention provides a polymeric salt, wherein the monomer unit of the polymeric salt comprises two nitrogen containing heterocyclic groups joined by a rigid linker group. The nitrogen atoms of the heterocyclic groups are disposed so as to enable a polymeric carbene formed by from the polymeric salt to complex with a metal atom. The invention also provides a polymeric metal complex which may be made from the polymeric salt, and which may be used in a Suzuki coupling reaction. The polymeric salt may be used as a heterogeneous organic catalyst for cyanation reaction.

    摘要: The present invention relates to methods for accelerating the trans-cis isomerization of 1,2-diphenylethylene analogues by using photocatalyst. According to this invention, in the presence of polypyridyl platinum(II) complex with catalytic dosage, a solution containing trans-1,2-diphenylethylene analogues or mixture of cis- and trans-1,2-diphenylethylene analogues is irradiated by visible light to prepare product of cis-1,2-diphenylethylene analogues or product predominantly being cis-1,2-diphenylethylene analogues under inert gas atmosphere. This method has the advantages of fast reaction, high performance, easy separation of reaction system and recycle of the polypyridyl platinum (II) complexes.
