Synthesis, Structure, and Spectroscopy of (Thiapentadienyl)rhodium Phosphine Complexes1
摘要:
The reactions of (Cl)Rh(PR3)(3) (R = Me, Et) with the anionic thiapentadienide reagent lithium 2,3dimethyl-5-thiapentadienide have been investigated. In each case, the kinetic product exhibits a thiapentadienyl bonding mode in which the sulfur atom is a-bonded to rhodium; however, ligand rearrangement yields thermodynamic isomers in which the carbon end of the thiapentadienyl chain is a-bonded to rhodium.
