| Abstract
| - The reactivity of the bifunctionalized ligand NC(Br)N-I 1 [IC6H2(CH2NMe2)2-3,5-Br-4] has beenstudied as a versatile synthon for organic and/or organometallic synthesis. Chemoselective metalation (M= Pd, Pt, Li) at the Caryl−I or Caryl−Br bonds was achieved by choosing the appropriate metal precursors.In this way a series of PtII and PdII complexes were prepared that have a second functional group availablefor further reactions. These PtII and PdII complexes were subjected to a wide range of organic andorganometallic reactions, revealing the remarkable stability of their M−C σ-bond and opening an easyroute for the synthesis of mono- and (hetero)bimetallic building blocks. The scope of the chemistry of suchbuilding blocks shows that they are good candidates for use in the synthesis of dendrimers, bioorganometallicsystems, or polymetallic materials. The X-ray crystal structures of the most representative complexes(2, 3a, 19, 20, and 24) are also reported.
