We demonstrate here two routes to synthesise the semiquinone complex [Ln(Tp)2(O,Oʹ-pd)] 1-Ln (Scheme 1). We have previously shown that potassium hydride (KH) is competent for single-electron reduction of pd 0 , was added to a yellow suspension of pd in THF, followed by addition of excess KH, a deep red-orange solution resulted from which 1-Ln (Ln = Yb, 74%; Dy, 68%) were isolated as brick-red solids (Route A). The solubility of 1-Ln is high in polar solvents and low in non-polar aromatic solvents.
