T1 - Synthesis of [(tmeda)LiCH2PMe2Li(tmeda)CH2PMe2] (tmeda = tetramethyl- ethylenediamine) and of a binuclear zirconocene phosphine functionalized ketene complex, [(η-C5H5)2CIZr(PMe2CH=CO)ZrCI(η-C5H5)2] (both structurally characterized), the latter via carbonylation of ‘[(η-C5H5)2ZrCI(CH2PMe2)]’

N2 - Reaction of [(tmeda)LiCH2PMe2Li(tmeda)CH2PMe2), (1), (tmeda = tetramethylethylenediamine) with [(η-C5H5)2ZrCy in tetrahydrofuran at -78 °C yields [(η-C5H5)2Zr(CH2PMe2)nCl2−n], n = 1, (2), or n = 2, (3); carbonylation of (2) affords exclusively a novel binuclear ketene complex, [(η-C5H5)2CIZr(PMe2CH=CO)ZrCI(η-C5H5)2], (4), which in the crystal form possesses a Zr-P linkage [2.724(5) Å].
