 Title    Oxyfunctionalization of Allyl Thioether Ruthenium Complexes with Dimethyldioxirane [1]  
 Abstract    Allyl thioether complexes [CpRu(P-P)(SRR')lPF6 (P-P = Ph2PCH2PPh2 (dppm), PIitPCtH-iPPI^ (dppe), R = Me, Et, Ph, R' = 3-propenyl, 3-cyclohexenyl, 2-methyl-2-buten-4-yl) and [CpRu(chir)(SRR')]PF6 (chir = (S,S)-Ph2PCHMeCHMePPh2, R = Me, CH2Ph, R' = 2-methyl-2-buten-4-yl) are obtained from the corresponding thiolate complexes by reaction with the appropriate allyl bromide. Careful oxidation with dimethyldioxirane (DMD) gave the allyl sulfoxide complexes [CpRu(P-P)(MeS(0)CH2CH=CH2)]PF6 (P-P = dppm, dppe). Double ox­ idation to the corresponding sulfinylmethyl epoxide complexes can be readily achieved with an excess of DMD. Oxidation of the chir complexes proceeds with only moderate diastereoselectiv-ity. The structure of the (/?, R/S, S) diastereomer of [CpRu(dppm)(MeS(0)CH2CHCH2 0)]PF6 was determined: monoclinic space group P2]/c (No. 14), a = 11.21(2), b = 16.762(9), c = 18.45(4) A, ß = 94.4(1)°, Z = 4. For a representative example, the decomplexation of the sulfoxide-epoxide ligand by sodium iodide in acetone was demonstrated.
