Organolanthanoid-halide synthons--a new general route to monofunctionalized lanthanoid(II) compounds?
New Eu(II) and Yb(II) complexes [Ln(Ph(2)pz)I(thf)(4)] were synthesized from the corresponding metals and 3,5-diphenylpyrazole (HPh(2)pz) using iodobenzene as oxidizing agent. In the absence of the pyrazole, the charge separated Yb(II)/Yb(III) complex [{Yb(dme)(4)}{YbPh(4)(dme)}(2)] has been isolated.
