ABSTRACT

The preparation of a new palladium(II) complex with a 2-pyridinealdoxime ligand and its use as a Pd(0) precatalyst in the cross-coupling Suzuki-Miyaura reaction is described. Several concepts for the immobilization of this catalytic system are presented and compared in order to develop an efficient catalytic tool for high-throughput synthesis.
