Efficient Preparation of Terminal Conjugated Dienes by Coupling of Dienol Phosphates with Grignard Reagents under Iron Catalysis was written by Cahiez, Gerard;Habiak, Vanessa;Gager, Olivier. And the article was included in Organic Letters in 2008.Reference of 50767-78-7 The following contents are mentioned in the article:

An efficient new route to prepare stereoselectively terminal conjugated dienes, e.g. (E)-n-C₈H₁₇CH:CHCH:CH₂, by coupling Grignard reagents and dienol phosphates, e.g. (E)-H₂C:CHCH:CHOPO(OEt)₂, in the presence of Fe(acac)₃ is described. The synthetic utility of this new iron-catalyzed procedure is illustrated by the synthesis of the pheromone of Diparopsis castanea according to a very expeditious strategy. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Reference of 50767-78-7).

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Reference of 50767-78-7

Synthesis of both geometric isomers of the major sex pheromone of the red bollworm moth was written by Nesbitt, Brenda F.;Beevor, P. S.;Cole, R. A.;Lester, R.;Poppi, R. G.. And the article was included in Tetrahedron Letters in 1973.Application of 50767-78-7 The following contents are mentioned in the article:

Wittig reaction of Ph3P+CH2CH:CH2Br- with AcO(CH2)8CHO gave a 60:40 trans:cis mixture of AcO(CH2)8CH:CHCH:CH2 (I). The trans isomer was separated as a cyclic sulfone which decomposed stereospecifically. Treatment of the Wittig product with (NC)2C:C(CN)2 and separation from the Diels-Alder adduct gave pure cis isomer. The isomeric purity of I was determined by gas liquid chromatog. of the products of epoxidation or terminal double bond reduction The natural pheromone contained 15-25% cis isomer. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Application of 50767-78-7).

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

EtAlCl₂, which is a strong Lewis acid and a proton scavenger, catalyzes the ene reactions of aliphatic aldehydes with nonnucleophilic alkenes. Higher aldehydes give good yields of ene adducts with terminal alkenes. CH₂O gives good yields of adducts with electron-deficient alkenes.

In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Computed Properties of C14H24O2

Carbon-13 NMR analyses on conjugated dienic pheromones of Lepidoptera was written by Ando, Tetsu;Kusa, Koji;Uchiyama, Masaaki;Yoshida, Shigeo;Takahashi, Nobutaka. And the article was included in Agricultural and Biological Chemistry in 1983.Computed Properties of C14H24O2 The following contents are mentioned in the article:

The ¹³C NMR of all the geometrical isomers of 5,7- and 8,10-dodecadien-1-ols and 9,11-dodecadienyl acetate were assigned from the examination of ¹³C chem. shift differences of olefinic C atoms induced by diene and chain substitution and by the chem. shift changes of allylic and olefinic C atoms due to geometry conversion of the conjugated diene system. These correlations comprise a new method for assigning the ¹³C NMR of conjugated systems. The ¹H NMR of the dienols and their derivatives were also discussed. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Computed Properties of C14H24O2).

(E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Computed Properties of C14H24O2

A novel palladium-catalyzed deoxygenation of ene diols to 1,3-dienes was written by Trost, Barry M.;Tometzki, Gerald B.. And the article was included in Synthesis in 1991.Quality Control of (E)-Dodeca-9,11-dien-1-yl acetate The following contents are mentioned in the article:

Hydroxylative Knoevenagel condensation of aldehydes followed by reduction provides a simple entry to 1,4-ene diols e.g. I (R = H). Subjecting the dicarbonate e.g. I (R = CO₂Me) to a Pd catalyst in the presence of (Me₂CHO)₃P achieves a mild vinylogous deoxygenation to (E)-1,3-dienes, e.g. II.
