Efficient, Ultrafast, Microwave‐Assisted Syntheses of Cycloplatinated Complexes

Cyclometallated chloridoplatinum complexes containing neutral monodentate ligands such as 2‐phenylpyridine (1a), 2‐(2′‐thienyl)pyridine (1c) or 4‐methoxypyridine (1d), as well as the cyclometallated benzo[h]quinoline chlorido complex with 4‐methoxypyridine (2d), can be synthesised in a few minutes by irradiating the reaction mixture with microwaves. The single‐crystal X‐ray molecular structures of the solvato complexes 1·dmso and 2·dmso as well as 1c, 1d and 2d are reported. The availability of this class of complexes in a few minutes offers the possibility of a combinatorial approach for the preparation of libraries of homologous compounds of potential interest for applicative purposes.
