The specification discloses a novel process for the preparation of 11-tetradecenal and novel intermediates therefor. There is also disclosed processes for the intermediates. The novel intermediates include 1,1-dialkoxy-9-halo-nonane and 1,1-dialkoxy-11-tetradecene. There is further disclosed a process for preparing a mixture of cis- and trans-11-tetradecenal at the molecular ratio of approximately 1-cis-form to 9 trans-form, by reacting a Grignard reagent of 1,1-dialkoxy-9-halo-nonane with a mixture (approximately 60:40) of 1-chloro-2-pentene and 3-chloro-1-pentene and thereafter hydrolyzing thus formed 1,1-dialkoxy-11-tetradecene. 11-Tetradecenal is useful as a sex pheromone against the female eastern spruce budworm (Choristoneura fumiferana). The 9:1 ratio of trans/cis isomers is believed to be the most effective ratio to use against the budworms.
Their isomers about the C═N bond showed ∼60–40% E–Z-ratio in organic solutions. Surprisingly, their confinement in a water-soluble capsule with benzoselenodiazole walls shows high selectivity for the cis-/Z-isomer. Their relative affinities for the chalcogen-bonded capsule at room temperature depend mainly on the guest chain length and functional groups. A chain length of 14 heavy atoms showed especially

A process for preparing functional group-containing olefinic compounds comprising the steps of (a) reacting (1) at least one functional group-containing nucleophile with (2) at least one carbonyl-containing compound that comprises at least one group that is a leaving group, or that is capable of subsequent conversion to a leaving group, and that optionally comprises one or more isolated carbon to carbon double or triple bonds, to form the corresponding functional group-containing carbonyl-containing compound, said carbonyl-containing compound being selected from the group consisting of ketones and aldehydes; and (b) reacting said functional group-containing carbonyl-containing compound with at least one alkylidene phosphorane comprising an alkylidene moiety and three other moieties bonded to its phosphorus atom, said alkylidene moiety optionally comprising one or more carbon to carbon double or triple bonds, to form a functional group-containing olefinic compound.
