WebNov 29, 2024 · The first example of the OCPPCO ligand, diisophosphaethynolate, is reported via reductive coupling of a Sc−OCP precursor. Upon reduction with KC 8, isolation of the dinuclear complex, namely [K(OEt 2)] 2 [(nacnac)Sc(OAr)] 2 (OCPPCO), is observed, leading to a unique motif [OCPPCO] 4−, stabilized by two scandium centers.Detailed NMR spectra … WebMay 1, 2000 · ABSTRACT.
