Usage

General Description

1,5-Decadiyne, also known as 1,5-Diyne, is a chemical compound with the molecular formula C10H14. It is a colorless liquid that is highly flammable and reactive. 1,5-Decadiyne is primarily used in organic synthesis and as a monomer in the production of polymers. It is also used in the manufacturing of pharmaceuticals, agrochemicals, and electronic materials. Due to its highly reactive nature, 1,5-Decadiyne must be handled with care and stored in a cool, dry place away from heat and sources of ignition. It is important to use appropriate safety measures and protective equipment when working with this compound.

Intermediate for Gossyplure, the sex pheromone of the pink bollworm

The sex pheromone of the pink bollworm (Pectinophora gossypiella) is an approximate 1:1 mixture of (Z,Z)- and (Z,E)-7,11-hexadecadienyl acetate; this sex pheromone, the above-identified mixture of isomers, is known as Gossyplure. A component of Gossyplure, (Z,E)-7,11-hexadecadienyl acetate, is the sex pheromone of the Angoumois grain moth (Sitotroga cerealella) and is known as Angoulure. An isomeric component of Gossyplure, the Z,Z isomer, elicits no response from the male Angoumois grain moth and it appears that the relatively large amount of the Z,Z isomer in Gossyplure interferes with the Z,E isomer such that Gossyplure cannot be used as a substitute for Angoulure. The isomeric components of Gossyplure are manufactured by the butylation of the mono-anion of 1,5-hexadiyne to 1,5-decadiyne which is in turn alkylated with hexamethylene halohydrin or a protective derivative thereof, such as tetrahydropyranyl ether, to give the 7,11-hexadecadiynyl moiety which after acetylation and partial reduction affords (Z,Z)-7,11-hexadecadienyl acetate, one of the isomeric components of Gossyplure. The other isomeric component of Gossyplure, the Z,E isomer, which is also known as Angoulure, the sex pheromone of the Angoumois grain moth, is synthesized from deca-(E)-5-enyne, (prepared by sodium-liquid ammonia reduction of 1,5-decadiyne) in an analogous manner.
