Abstract
Hydroxyarylalkenes, particularly the ones constituting cashew nut shell liquid, are converted to (hydroxyalkyl)phenols, particularly 3-(8-hydroxy-noctyl)phenol, by ozonolysis followed by reduction, preferably with a hydride such as sodium borohydride. No protective acylation of the hydroxyarylalkenes is necessary. The resulting (hydroxyalkyl)phenols are useful for the preparation of polycarbonates.
