✦ Synopsis


The h&a&&n A hteheunpec&Lc @t b&h CA and Ruthenium oxides are extremely powerful oxidising reagents which have been extensively used in oxidative transformations in organic chemistry'. These reactions involve the use either of a stoechiometric amount of ruthenium tetroxide, or more conveniently of a ruthenium compound in a catalytic quantity with a stoechiometric amount of a readily available oxidant. Many different catalyst-oxidant systems have been described, the most common of which involve RuC13,(H20), as catalyst and hypochlorite or periodate as oxidant. Generally, the reactions are conducted in a two-phase solvent system such asCC14-H20 Recently it has been shown by Sharpless that addition of acetonitrile as a cosolvent gives greatly improved results2.

Ruthenium complexes of the type [RuX(Cp%)(PPh 3 ) 2 ] (X=Cl and H; Cp%=Cp, Cp\*, indenyl, and carboranyl) efficiently catalyse olefin cyclopropanation with diazoesters, and the cis/trans stereoselectivity of the resulting cyclopropanes strongly depends on the Cp% ligand.

A synthetic strategy was developed to anchor an amino acid L-valine on to styrene-divinylbenzene co-polymer beads with 8% and 6% cross linking. The polymeric ligands containing bidentate N,O donor sites were treated with a solution of ruthenium(III) chloride to form the metal complex on the support.
