A stoichiometric solvent-free protocol for acetylation reactions was written by Valentini, Francesca;Galloni, Pierluca;Brancadoro, Diana;Conte, Valeria;Sabuzi, Federica. And the article was included in Frontiers in Chemistry (Lausanne, Switzerland) in 2022.SDS of cas: 112-14-1 The following contents are mentioned in the article:
Considering the remarkable relevance of acetylated derivatives of phenols, alcs., and aryl and alkyl thiols in different areas of biol., as well as in synthetic organic chem., a sustainable solvent-free approach to perform acetylation reactions is proposed here. Acetylation reactions are classically performed using excess of acetic anhydride (Ac2O) in solvent-free conditions or by eventually working with stoichiometric amounts of Ac2O in organic solvents; both methods require the addition of basic or acid catalysts to promote the esterification. Therefore, they usually lead to the generation of high amounts of wastes, which sensibly raise the E-factor of the process. With the aim to develop a more sustainable system, a solvent-free, stoichiometric acetylation protocol is, thus, proposed. The naturally occurring phenol, thymol, can be converted to the corresponding-biol. active-ester with good yields, in the presence of 1% of VOSO4. Interestingly, the process can be efficiently adopted to synthesize other thymyl esters, as well as to perform acetylation of alcs. and aryl and alkyl thiols. Remarkably, a further improvement has been achieved replacing Ac2O with its greener alternative, isopropenyl acetate (IPA). This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1SDS of cas: 112-14-1).
Octyl acetate (cas: 112-14-1) 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. 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.SDS of cas: 112-14-1
