unsaturated peroxidic compounds have been prepared, characterized and inductively decomposed in various solvents to afford the corresponding oxiranes. The reaction proceeded by a radical chain mechanism and was initiated either by thermolysis of added t-butyl peracetate at 110°C or AIBN at 80°C, or by autoxidation of BEt3 at 20°C. The studied peroxyderivatives were designed to generate oxyl radicals reacting
catalytic amount of iron(II) triflate, TIPS-protected peroxides bearing primary, secondary, and tertiary C-H sites undergo chemoselective thioetherification of remote C-H bonds with diaryl disulfides. The reaction demonstrates a broad substrate scope and functional group tolerance without the use of any noble metal additives. Mechanistic experiments suggest that the reaction proceeds through 1,5-H atom
Reaction of alkyl hydroperoxides (1ary, 2ary or 3ary) upon tertiary alkyl trichloroacetimidates under acidic catalysis yielded unsymetrical dialkyl peroxides with yields in the range 30-70%.
