2-methyl cyclohexyl acetate method for the synthesis of (by machine translation)
-
Paragraph 0080-0085, (2017/03/18)
The invention discloses a 2-methyl cyclohexyl acetic acid ester synthetic method, including (1) hydrogenation reaction: the O-cresol in dissolved in methyl cyclohexane, then adding hydrogenation catalyst and high purity hydrogen, after the hydrogenation reaction, with 2-methyl-cyclohexanol of a hydrogenation reaction liquid ; (2) the esterification reaction: the hydrogenation reaction of esterification catalyst and the liquid are added to a reaction vessel, using acetic acid as the esterifying agent, stirring the mixed solution is dropped to the central area, to undergo esterification reaction, to obtain 2-methyl cyclohexyl acetate. The synthetic method of this invention can effectively improve the 2-methyl cyclohexyl acetate synthetic yield, fixed asset investment is reduced, the running cost is reduced, simplifying the production process complexity.

Silica-supported boric acid (H3BO3-SiO2) has been established as a green, efficient and recyclable catalyst for the synthesis of dihydropyrimidin-2-ones, bis(indolyl)methanes, and acetylation of alcohols, phenols, amines and thiols under solvent free conditions. The main features of the present method include clean reaction, mild conditions, low loading of environment friendly catalyst and easy workup procedure. The catalyst can be recycled at least five times without any significant loss in activity.
Iron (III) phosphate as a green and reusable catalyst promoted chemo selective acetylation of alcohols and phenols with acetic anhydride under solvent free conditions at room temperature

experimental part, p. 633 - 637 (2011/10/08)
Iron (III) phosphate was employed as an efficient catalyst for the chemo selective acetylation of alcohols and phenols under solvent free condition at room temperature and with high yields. Iron (III) phosphate is also a potential green catalyst due to solid intrinsically, reusable and with high catalytic activity.

N-Heterocyclic carbenes (NHC) are efficient catalysts for transesterification/acylation reactions involving secondary alcohols. The catalytic transformations are carried out employing low catalyst loadings in convenient reaction times at room temperature.
Meerwein-Ponndorf-Verley-type reductive acetylation of carbonyl compounds to acetates by lanthanide complexes in the presence of isopropenyl acetate
Nakano, Yasushi,Sakaguchi, Satoshi,Ishii, Yasutaka
, p. 1565 - 1569 (2007/10/03)
Meerwein-Ponndorf-Verley-type reductive acetylation of carbonyl compounds to acetates was successfully carried out in the presence of isopropenyl acetate under the influence of a catalytic amount of Ln(O(i)Pr)3 at room temperature. Various carbonyl compounds were converted into the corresponding acetates in fair to good yields. (C) 2000 Elsevier Science Ltd.

A variety of alcohols are converted into the corresponding acetates upon treatment with acetic anhydride and catalytic amount of chlorotrimethylsilane in acetonitrile (or dichloromethane).
Anti-Markovnikov Addition of Nucleophiles to a Non-conjugated Olefin via Single Electron Transfer Photochemistry
Gassman, Paul G.,Bottorff, Kyle J.
, p. 5449 - 5452 (2007/10/02)
Nucleophilic solvent has been added regiospecifically in an anti-Markovnikov manner to a simple non-conjugated olefin, 1-methylcyclohexene, through single electron transfer induced photochemistry using the 1-cyanonaphthalene - biphenyl pair for achieving photooxidation.

The acetolysis of a series of bicycloalkanes and propellanes has been studied.The effect of ring strain, caused by changing ring size or introducing a trans-ring fusion, on the rate and products of the reaction has been examined.No correlation was found between rates of acetolysis and strain energy relief, but with the exception of propellane, there is a rough correlation with ionization potentials.The degree of polarization of the C-C bonds in the presence of a proton correlates very well with reactivity and is a controlling factor for the acetolysis rates.The importance of the energies of unoccupied orbitals with the appropriate symmetry in controlling electron polarization is shown by the large difference in rate of reaction between - and propellanes.
