Ruthenium colloids: A new catalyst for alkane oxidation by tBHP in a biphasic water-organic phase system

Efficient and highly selective conversion of cyclooctane into cyclooctanone is obtained under pure biphasic conditions through t-butylhydroperoxide activation by the in situ formation of colloidal ruthenium species arising from RuCl3, 3H2O. Model extension experiments to other cycloalkanes are also discussed.

Oxymetallation. Part 16. Modified Procedures for Reducing Peroxymercurials: Conversion of Non-terminal Alkenes into Secondary Alkyl t-Butyl Peroxides

Various procedures for reducing PhCH(OOBut)CH2HgO2CCF3 or PhCMe(OOBut) have been investigated in an attempt to optimize yields of the mercury-free peroxides.Effects of varying the concentration of borohydride and the mode of mixing, and of including a phase transfer catalyst, have been assessed for the two phase system of alkaline NaBH4 and dichloromethane and reductions have been carried out in a single phase by using Bu4NBH4 in dichloromethane.The t-butyl peroxymercurials t)CH(HgX)R> derived from cis- and trans-but-2-ene, cis- and trans-hex-3-ene, cyclopentene, cyclohexene, and norbornene have been reduced under the optimum conditions of slowly adding base-pretreated peroxymercurials in dichloromethane to a large excess of alkaline NaBH4.Product analyses support the idea that the reactions proceed via β-peroxyalkyl radicals t)CHR>, but show that, except for the norbornyl derivative, epoxides are the dominant products; cyclopentyl, cyclohexyl, and exo-norbornyl t-butyl peroxides have been isolated in yields of 2, 13, and 37 percent, respectively.Better, but still modest, yields (24-36 percent) have been obtained for butan-2-yl, hexan-3-yl, and cyclopentyl t-butyl peroxides by silver trifluoroacetate-assisted t-butyl perhydrolysis of the alkyl bromides, but competing dehydrobromination lowered the yield (6 percent) of the cyclohexyl compound.Vastly improved yields (ca. 60 percent) of butan-2-yl, cyclopentyl, and cyclohexyl t-butyl peroxides have been achieved by reduction of the corresponding peroxymercurials with neat Bu3SnH.
