Stephan*:Synthesis, Structure and Bonding in Zirconocene Primary Phosphido (PHR-), Phosphinidene (PR2-), and Phosphide (P3-) Derivatives. Page 1918. One of the compounds reported in this The synthesis, paper is Cp2Zr(PH(2,4,6-C~H2Me3))Cl. structure, and some related reactivity were described. In fact, an earlier report of the preparation of this compound had appeared and was overlooked in the references (Hey, E.; Muller, U. 2. Naturforsch. 1989, 44B, 1538). In addition, we erroneously reported the 31Pchemical shift as 43.0ppm; the chemical shift is -4.3 ppm in THF. The chemical shift of -5.7 ppm (IJP-HI = 230 Hz) in benzene was reported earlier by Hey and Muller. OM950423N

Pages 3328-3329. The 27Alchemical shifts of compounds 2, 4, and 5 were misassigned. The correct values are 6 52 for compound 2,d 118 for compound 4, and 6 110 for compound 5. OM950402T
