Abstract
The reaction of [RuCl₂(CO)₃]₂ and Te₂Tpn₂ (Tpn=thiophen-2-yl, C₄H₃S) in the absence of light resulted in the formation of cct-[RuCl₂(CO)₂(TeTpn₂)₂] (1) [cis(Cl)-cis(CO)-trans(TeTpn₂)] and TeTpn₂ (2) together with the precipitation of tellurium. The complex 1 and the monotelluride 2 were characterized by NMR spectroscopy and single-crystal X-ray diffraction. The decomposition of Te₂Tpn₂ to TeTpn₂ has been monitored by ¹²⁵Te NMR spectroscopy and seemed to be faster than the ligand substitution in [RuCl₂(CO)₃]₂ by TeTpn₂. A catalytic cycle is proposed for the decomposition of Te₂Tpn₂ to TeTpn₂ based on the PBE0-D3/def2-TZVP calculations.
