Popis:	The reactivity of [Pd(dippe)(μ-H)]2 (1) and [(μ-dippe)Pd]2 (2) (dippe = 1,2-bis(diisopropylphosphino)ethane) toward C–S bonds in thiophene derivatives and thioethers was investigated, which led to C–S bond activation products. The thiapalladacycles derived from thiophenic substrates were fully characterized by 1H, 31P, and 13C NMR spectroscopy, elemental analysis, and X-ray diffraction. The stability of the C–S insertion products was probed by performing competition experiments which follow the thermodynamic stability order (dippe)Pd(κ2C,S-benzothiophene) (6) > (dippe)Pd(κ2C,S-dibenzothiophene) (8) > (dippe)Pd(κ2C,S-thiophene) (3). The reactivity of the thiapalladacycles with small molecules such as H2, CO, and alkynes was investigated.
