Synthesis and characterization of cobalt SCS pincer complexes

Abstract

AbstractThe synthesis and characterization of two Co(II) complexes stabilized by a tridentate SCS pincer ligand are described. Paramagnetic [Co(κ3-SCSCH2-Et)2] and [Co(κ3-SCSCH2-tBu)(κ2-SCSCH2-tBu)] were obtained via transmetalation protocol from CoBr2 and S(C-Br)SCH2-R (R = Et, tBu). Oxidation of the latter with [Cp2Fe]PF6 affords the diamagnetic 18 VE complex [Co(κ3-SCSCH2-tBu)2]PF6. X-ray structures and DFT calculations are presented. Graphical abstract
