Temperature200 °C

Reaction Steps

A mixture of 200 parts of mesityl oxide, 200 parts of geraniol and 400 parts of tetrahydrofuran has 0.01 part of p-toluenesulfonic acid added to it and the whole is heated for 3 hours at 200°C at 50 atmospheres pressure. The reaction mixture is distilled and 133 parts of 4,8,12-trimethyl-3,7,11-tridecatrien-2-one is obtained. At a conversion of 52% the yield is 78% of theory based on geraniol.
