To a stirred mixture of cycloheptanone (73.2 g.) and ethanol (200 cc.), containing ammonium acetate (6.4 g.) and kept at or below 0°C was added 1-amino-3,3,5-trimethylcyclohexyl hydroperoxide (69.2 g.; 76% pure). After the solid had dissolved (5 hours) the solution was stored at 0°C overnight and the product worked up as in the previous Examples. There were obtained unreacted cycloheptanone, and dihydroisophorone, and fractions (57.5 g.) b.p. 124° - 130°C/0.3 mm.Hg., peroxide equivalent 283, perchloric acid equivalent 278 shown by mass spectroscopy to contain the peroxide ##SPC63##
