  P−B Adducts of 3,4‐Dimethyl‐1‐phosphaferrocene with Bromoboranes

  摘要：

  AbstractThe crystalline adducts FcP−BBr3 (2) and FcP−BBr2Fc (3), which are very rare examples of P‐bonded complexes between phosphaferrocene and a main‐group metal atom, were obtained by the reaction of 3,4‐dimethyl‐1‐phosphaferrocene (FcP) with BBr3 and FcBBr2 (Fc: ferrocenyl). According to X‐ray crystallography, the Fe−P bond length in 2 is 0.085 Å shorter than in the parent phosphaferrocene. All structural changes resulting from P−B acid−base pairing follow the same qualitative trend, but are significantly larger than those occurring from the formation of transition metal complexes of phosphaferrocene. In contrast to 2, NMR spectroscopy reveals 3 to be almost completely dissociated in CDCl3 solution at room temperature. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
