Cyclohexanone → Cyclohexene-1-yl acetate

Participants

Reaction Steps

Acetic acid in an amount of 15.1 g. was reacted with 6.1 g. cyclohexanone over the catalyst (0.5 g.) described in Example 1. The reaction started at room temperature (25°C.) in the presence of hydrogen and was stopped after 95 minutes, the temperature reaching a high of 84°C. by application of heat. Cyclohexyl acetate was identified as a reaction product by VPC analysis. This reaction in the presence of Amberlyst-15 resin gives a small amount of 1-acetoxycyclohexene; with conventional platinum-on-alumina catalyst it gives cyclohexanol; and with a loose physical mixture of Amberlyst-15 resin and the conventional platinum-on-alumina, the product is cyclohexanol. By "loose" physical mixture is meant a slurry of the type described in Example 2.
