Abstract
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.
