, p. 764 - 766 (1997)
Allyl trichloroacetate and allyl 2,2-dichloropropionate, unlike allyl bromoacetate and allyl 2-bromopropionate, undergo cyclization into γ-lactones in the presence of a Fe(CO)5-amide system. All these esters undergo reductive dehalogenation under the action of the Bun3SnH-AlBN system.

, p. 11823 - 11830 (2021/07/11)
In this work, FeNi layered double hydroxides/graphene oxide (FeNi LDH/GO) was prepared, which exhibits excellent selective cataluminescent performance towards propylene oxide. The selectivity and sensitivity of the cataluminescence (CTL) reaction were investigated in detail. Moreover, the catalytic reaction mechanism, including the intermediate products and the conversion of reactants to products, was discussed based on both the experimental and computational results. Furthermore, the proposed FeNi LDH/GO based CTL sensor was successfully applied for the determination of propylene oxide residue in fumigated raisins, which indicates extensive application potential for rapid food safety evaluation.

Paragraph 0038-0039, (2019/07/04)
The invention discloses a method for preparing propionate by ester alcohol exchange, and relates to a method for preparing propionate. According to the invention, the method for synthesizing propionate by ester alcohol exchange of methyl propionate and various alcohols (including monohydric alcohols such as ethanol, propanol, butanol, tert-butanol, isopropanol, cyclohexanol, allyl alcohol and thelike, dihydric alcohols such as 1,3-propylene glycol and the like, glycerol and the like) is adopted, and methyl propionate and the alcohols are used as raw materials to carry out a reaction under catalysis of alkaline ionic liquid, soluble strong alkali or solid alkali to prepare higher propionate and methanol. According to the method, the synthetic route is short, and the reaction product is taken out through azeotropic extraction of the methyl propionate and methanol, so that the reaction is more thorough, and the target product is directly obtained by one step. The product obtained by thereaction only contains propionate and methanol, the whole reaction process is concise and efficient and is free of pollution, no byproducts are generated, and great significance is achieved for large-scale and low-cost production of propionate.

, p. 1558 - 1561 (2013/09/12)
A series of unsaturated esters were prepared via condensation of sodium carboxylates and alkenyl halide under the condition of macroporous polystyrene grafted quarternary ammonium salt as recyclable phase transfer catalyst, NaI as co-catalyst, Cu powder as inhibitor and H2O as solvent. Under optimal conditions, products yields are 78.2～ 96.0%. The catalyst can be convenient recycled and reutilized for about five times without losing its activity obviously.

Using the method of competitive reactivity of two functional groups in the same molecule, anionic elimination reactions show considerable kinetic selectivity for small differences in leaving group thermochemistry, in structures of the general type YCH2CH2CH2Z, where Y and Z are good anionic leaving groups.

D'yachkov, A. I.,Likhterov, V. R.,Etlis, V. S.
, p. 829 - 832 (2007/10/02)
The kinetics of the esterification of substituted carboxylic acids with allyl alcohol were studied.The reaction is of first order in the catalyst and in the substrate, and the equilibrium under the investigated conditions is shifted toward the formation of the ester.The observed enthalpy of activation does not depend on the substituent, and the difference in the reactivities of the investigated compounds is determined entirely by the entropy component of the free energy.
