Abstract

When a-pinene oxide in quinaldine solution is treated with catalytic amounts of ptoluenesulfonic acid, about 30% of the oxide is converted to a mixture of aldehydes. The remainder of the a-pinene oxide is converted to a mixture of hydrocarbons. The aldehyde fraction consists of a-campholenic aldehyde, 85%, and a new aldehyde identified as 2, 2, 4- trimethyl-3-cyclopentene-l-acetaldehyde. The hydrocarbon fraction consists of four ...
