Structure of Peroxides Derived from Cyclohexanone and Hydrogen Peroxide

摘要

Cyclohexanone and aqueous hydrogen peroxide react in the absence of mineral acid catalyst to form 1,1-dihydroxydicyclohexyl peroxide(I).In the presence of traces of mineral acids, however, the only product is 1-hydroxy-1’-hydroperoxydicyclohexyl peroxide(V).Since I can be converted to V by action of hydrogen peroxide and traces of mineral acids. I spears to an intermediate in the formation of V. That 1-hydroxy-1-hydroperoxy cyclohexans (II)is also an intermediate in these reactions is suggested by the fact that the 2-chioro and 2-bro analogues of II certainly are products of the reactions between hydrogen peroxide with the corresponding 2-halocyclohexanones. The decompositions of I an V by ferrous ion have been reinvestigate. Several related peroxides have been prepared. and their infrared spectra recorded.
