Reaktionsschritte

To a stirred mixture of cyclopentanone (33.8 g.) and ethanol (100 c.c.) containing ammonium acetate (3.2 g.) and kept at or below 0°, was added 1-amino-3,3,5-trimethylcyclohexyl hydroperoxide (44.6 g., 68% pure). After storing at 0°C overnight the reaction mixture was worked up as in the previous Examples to give unreacted cyclopentanone and dihydroisophorone together with a fraction (20.0 g.) b.p. 82° - 86°/0.5 mm. This last fraction was redistilled to give: material b.p. 74° - 76°C/0.3 mm.Hg., peroxide equivalent 202, shown by mass spectroscopy to be a mixture of the peroxide ##SPC28##
