TRANS-2-NONENAL Chemical Properties,Usage,Production
Chemical Properties
CLEAR COLOURLESS TO PALE YELLOW LIQUID
Uses
trans-2-Nonenal is an unsaturated aldehyde that is a product of fatty acid peroxidation (and also has a grassy, cucumber smell). trans-2-Nonenal is naturally found in mushrooms, coffee and is also a constituent of carrot root. It also exhibits insecticidal effects.
Definition
ChEBI: (E)-non-2-enal is a monounsaturated fatty aldehyde that is (2E)-non-2-ene which is carrying an oxo group at position 1. It has a role as a plant metabolite. It is a monounsaturated fatty aldehyde, an enal and a medium-chain fatty aldehyde.

General Description
trans-2-Nonenal (T2N) is a volatile unsaturated aldehyde with an unpleasant greasy odor, present in low concentrations in barley, malt, and certain vegetables. It is utilized as an insect repellent, insecticide, and flavor compound. T2N is one of the basic components contributing to the off-flavor and odor in stored beer.
Synthesis
(1), the synthesis of -phenylthio-nonenal
Take n-nonynyl (0.12 g, 1 mmol), phenylthiophenol (2a) (0.33 g, 3 mmol) was dissolved in chloroform, the reaction was carried out at 20 ; the reaction was tracked by TLC until it was completely finished; the crude product obtained at the end of the reaction was separated by column chromatography (petroleum ether: ethyl acetate=10:1), the target product was obtained (yield 84%);
(2) Synthesis of target product (E)-2-nonenal
Weighing -phenylthio-nonenal (3f) (0.25 g, 1 mmol) was dissolved in 10 mL of dichloromethane, and aqueous hydrogen peroxide (0.22 g, 2 mmol, 30%) was added drop by drop at 0 with continued stirring for 3 h. Ten milliliters of water was added, and the reaction was carried out under 30 with stirring. The reaction was stirred and followed by TLC until the complete completion of the reaction; after the reaction, the reaction solution was poured into a saturated solution of sodium bicarbonate, the aqueous phase was extracted by adding dichloromethane, the organic layers were combined, washed by adding saturated solution of sodium bicarbonate, and then dried and concentrated with anhydrous magnesium sulfate. The crude product was separated by column chromatography (petroleum ether:ethyl acetate=10:1) to obtain the target product (E)-2-nonenal (83% yield)
