Synthesis of [(tmeda)LiCH2PMe2Li(tmeda)CH2PMe2](tmeda = tetramethyl-ethylenediamine) and of a binuclear zirconocene phosphine functionalized ketene complex, [(η-C5H5)2ClZr(PMe2CHCO)ZrCl(η-C5H5)2](both structurally characterized), the latter via carbonylation of ‘[(η-C5H5)2ZrCl(CH2PMe2)]’

Abstract
Reaction of [(tmeda)L[graphic omitted]Me2], (1), or (tmeda tetramethylethylenediamine) with [(η-C5H5)2ZrCl2] in tetrahydrofuran at –78 °C yields [(η-C5H5)2Zr(CH2PMe2)n, Cl2 –n]n= 1, (2), n= 2, (3); carbonylation of (2) affords exclusively a novel binuclear ketene complex, [(η-C5H5)2ClZ[graphic omitted]Cl(η-C5H5)2], (4), which in the crystal form possesses a Zr–P linkage [2.724(5)Å].Keywords
