Abstract

Reaction of [(tmeda)LiCH₂PMe₂Li(tmeda)CH₂PMe₂), (1), (tmeda = tetramethylethylenediamine) with [(η-C₅H₅)₂ZrCy in tetrahydrofuran at -78 °C yields [(η-C₅H₅)₂Zr(CH₂PMe₂)nCl_2−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].
