Intramolecular C(sp2)–C (sp2) bond formation between phenanthroline and β-diketone thiosemicarbazones in PtII complexes: crystal structures and computational studies

[PtCl2(phen)] reacts with thiosemicarbazones derived from β-diketones (H2LR) leading to an intramolecular C–C coupling between phen and the ketone upon formation of tetradentate N,N,N,S chelates [PtII(LRphen)]. The reactions proceed via bidentate coordination of the doubly deprotonated (LR)2− follow...

Zusammenfassung:[PtCl2(phen)] reacts with thiosemicarbazones derived from β-diketones (H2LR) leading to an intramolecular C–C coupling between phen and the ketone upon formation of tetradentate N,N,N,S chelates [PtII(LRphen)]. The reactions proceed via bidentate coordination of the doubly deprotonated (LR)2− followed by an intra-nucleophilic attack and consecutive C–C bond formation.
