Reaction Steps

Butyraldehyde (14.4 g.) was mixed with petrol (b.p. 40° - 60°) (50 c.c.) and to the stirred solution at below 0°C was added 1-amino-3,3,5-trimethylcyclohexyl hydroperoxide (17.3 g.; 89% pure). The peroxide dissolved within a few minutes. To the solution were added magnesium sulphate and concentrated sulphuric acid (6 drops) and the mixture stored at 0°C overnight. The solution was filtered, the filtrate washed with water, dried and distilled to give unreacted butyraldehyde, dihydroisophorone and a product (11.1 g.), b.p. 85° - 110°C/1.0 mm. with a peroxide equivalent of 231, and a perchloric equivalent of 233. The elemental analysis gave C, 68.6%; H, 11.05%; N, 6.6%. The product was identified as: ##SPC55##
