  Synthesis and Characterization of 1,1‘-Diphospharuthenocenes

  摘要：

  Reaction of [RuCl2(cod)](n) (cod = 1,5-cyclooctadiene) with lithium 2,5-dialkylphospholide or 1-stannyl-2,5-dialkylphosphole gives Ru(eta(5)-PC4H2-2,5-R-2)(2) (R = (-)-menthyl, 4a; or cyclohexyl, 4b). Steric bulkiness of the R groups is a crucial factor for the successful preparation of the 1,1'-diphospharuthenocenes. The structure of the complex 4b was studied by X-ray single-crystal structure determination, which clarified the distance between the nearly planar eta(5)-phospholyl ligand and the ruthenium center in the complex, being 1.811 Angstrom.

  A novel reaction mode of phosphametallocenes was discovered. The phospharuthenocenes with cyclohexyl substituents at the alpha-positions of the eta(5)-phospholide(s) reacted with acyl electrophiles by an initial electrophilic attack to the ruthenium to produce the mu-alkenylidene species with activation of the acyl C=O double bond and elimination of an alpha-hydrogen.
