  (η⁶‐Arene)ruthenium(II) Complexes with Hemilabile η³‐Dicyclohexylvinylphosphine (DCVP) and η³‐Diphenylvinylphosphine (DPVP) Phosphaallyl Ligands: Formation of an Unexpected Trinuclear Complex

  摘要：

  The complexes [(eta(6)-arene)RuCl2(Cy2PCH=CH2)], [arene=MeC6H5, (1a); p-MeC6H4Me; (2a); p-MeC6H4CHMe2 (3a); 1,2,4,5-Me4C6H2, (4a); and C6Me6, (5a)], have been synthesized by reacting [(eta(6)-arene)RuCl2](2) with dicyclohexylvinylphosphine (DCVP). In the presence of AgPF6, in a 1: 1 dichloromethane/acetone solvent mixture the compound [(eta(6)-C6Me6)RuCl2(Cy2PCH=CH2)] (5a) afforded [(eta(6)-C6Me6)RuCl(eta(3)-DCVP)]PF6 (1b). A similar reaction was conducted with [(eta(6)-C6Me6)RuCl2(Ph2PCH=CH2)] in an attempt to form [(eta(6)-C6Me6)RuCl(eta(3)-DPVP)]PF6 (2b). However, this reaction yielded, instead, the unexpected trinuclear heterobimetallic complex [{(eta(6)-C-6-Me-6)Ru(mu-Cl)(2)(Ph2PCH=CH2)}(2)Ag](PF6) (3b) the structure of which was determined by X-ray crystallography. Compound (1b) reacts with phenylisocyanide to form [(eta(6)-C6Me6)RuCl(eta(1)-DCVP)(CNPh)]PF6. The complexes have been characterized by H-1, P-31{H-1} and C-13(H-1) NMR spectroscopy, elemental analyses, cyclic voltammetry, and in some cases [compounds (4a), (1b) and (3b)] by X-ray crystallography.

  The reaction of [Ru(eta(6)-p-cymene)Cl-2](2) with the chiral Schiff base (S)-(alpha-methylbenzyl)-3,5-di-t-butylsalicylaldimine (HL*) in the presence of NEt3 in CH2Cl2, forms a diastereomeric mixture of (R-Ru, S-C)- and (S-Ru , S-C)-[Ru(eta(6)-p-cymene)(L*)Cl] (1a, 1b). The crystal structure of the complex shows the presence of both the diastereomers in 1:1 ratio in the triclinic space group P1. Both the structures exhibit the presence of a non-covalent CH-pi interaction involving two p-cymene ring protons and the phenyl group attached to the chiral carbon. The H-1 NMR spectra of the complex in CDCl3 display the presence of two diastereomers in a 88:12 ratio at room temperature. The absolute configuration of the major diastereomer in solution has been determined by 2D NOE measurements. Observation of NOE cross peaks involving the C*-H and the p-cymene ring protons indicates a (R-Ru - S-C)configuration of the major diastereomer in solution. (C) 2002 Elsevier Science Ltd.

The compounds [eta(6)-MeC6H5)RuCl2(Ph2AsCH=CH2)] (1a) and [eta(6)-1,3,5-Me3C6H3)RuCl2(Ph2AsCH=CH2)] (4a) undergo KOBut-promoted intramolecular hydroalkylation in boiling acetonitrile to produce tethered arsinopropylareneruthenium(II) complexes 1c and 4c, respectively. The complexes have been characterized by H-1 and C-13H-1} NMR spectroscopy, elemental analyses, cyclic voltammetry, and in several cases by X-ray crystallography.
