Abstract
There is disclosed a novel process for preparing a number of cinnamaldehyde derivatives. These cinnamaldehyde derivatives can be reduced to dihydrocinnamaldehyde derivatives, a number of which are commercially important in the preparation of fragrances. The invention is also directed to a number of novel intermediates and their preparation.
