And the article was included in Agriculture, Ecosystems & Environment in 1988.Product Details of 50767-78-7 The following contents are mentioned in the article:

The sex pheromone glands of the 3 most important tortricids of European vineyards, Eupoecilia ambiguella, Sparganothis pilleriana, and Lobesia botrana have been chem. investigated and found to contain up to 15 different straight-chain acetates and alcs. Behavioral observations in the wind tunnel and field trapping demonstrate that in each species at least 3 female-produced components are involved in male attraction. This study involved multiple reactions and reactants, such as (E)-Dodeca-9,11-dien-1-yl acetate (cas: 50767-78-7Product Details 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. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Product Details of 50767-78-7

And the article was included in Bulletin of the Korean Chemical Society in 2013.Electric Literature of C15H22O2 The following contents are mentioned in the article:

Atom-economical esterification is of great importance in green chem. The authors demonstrated the catalyst and additive free esterification of alcs. by their reaction with 2-acyl-4,5-dichloropyridazin-3(2H)- ones without solvent at 100°. Aliphatic and aromatic alcs. were converted into the corresponding esters in good to excellent yields. It is noteworthy that the reaction is solvent-free, atom-economic, easy-workup, and rapid and that the process is inexpensive. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Electric Literature of C15H22O2).

2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 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.Electric Literature of C15H22O2

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.

Rhodium-Catalyzed Carbonylative Synthesis of Aryl Salicylates from Unactivated Phenols was written by Ai, Han-Jun;Zhang, Youcan;Zhao, Fengqian;Wu, Xiao-Feng. And the article was included in Organic Letters in 2020.Quality Control of Diphenyl carbonate The following contents are mentioned in the article:

In the presence of RhCl₃ and 1,2-bis(dicyclohexylphosphino)ethane (dcpe), phenols underwent carbonylative esterification reactions with CO mediated by TEMPO in 1.4-dioxane/toluene to yield aryl salicylates such as Ph salicylate. Under similar conditions, but using 1,3-bis(diphenylphosphino)propane as the ligand, di-Ph carbonate was obtained as the major product. The mechanism of the reaction was studied using the reactions of potential intermediates and using kinetic isotope effects. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Quality Control of Diphenyl carbonate).

Diphenyl carbonate (cas: 102-09-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. 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.Quality Control of Diphenyl carbonate
