Starting with linaloöl, citral has been prepared by reacting a geranyl halide with alkali salts of nitro paraffines. By the same method other α,β-unsaturated carbonyl compounds were obtained, which are useful intermediates for the synthesis of carotenoids.

En remplaçant dans la réaction de Caroll l'ester acétylacétique par l'ester acétylacétique α-monochloré, on a réussi à préparer la dihydropseudo-ionone etla dihydro-pseudo-irone α-monochlorées, corps qui se laissent déchlorer respectivement en pseudo-ionone et pseudo-irone. C'est une nouvelle méthode de préparation de certaines cétones α-halogénées.
