Ru III Complexes with -P, -As, -Sb and -S Donors

RuBr(PPh3)(OEP) is made from Ru(PPh3)3(OEP) and Br. As RuBr(PPh3)(OEP)/ PhlO/CH Clj it epoxidised styrene, norbomene and cw-stilbene to their epoxides, but frawj-stilbene was not oxidised [588]. The reagent RuBr(PPh3)(OEP)/PhlO/CH3Cl2 oxidised cyclohexane and cyclohexene to a mixture of products [812]. 

Ru(OH)(PPh3)(salen) is made from Ru(NO)Cl3(PPh3)2, (salen=iV,iV -ethan-l,2-bis-(salicyliden-amine) and ethyldi-ixopropylamine in EtOH. As Ru(OH)(PPh3) (salen)/02/CH3Cl3 or CHCI3 it preferentially oxidised primary alcohols to aldehydes while l-phenyl-l,n diols (n = 2 to 5) were oxidised by Ru(PPh3)(OH)(salen)/ O /CHClj to lactols or the n-hydroxyaldehyde [813]. 

RuX3(EPh3)(tSB) (X=C1, Br E=P, As tSB=tridentate Schiff base made from anti-pyrine and salicylaldehyde, o-vanillin, o-phenylenediamine) are made from the
