Efficient and Rapid Solvent‐Free Acetylation of Alcohols, Phenols, and Thiols Using Catalytic Amounts of Sodium Acetate Trihydrate

Abstract

Under solvent-free conditions, different alcohols and phenols were efficiently acetylated at room temperature within short time periods by using acetic anhydride in the presence of catalytic quantities of sodium acetate trihydrate, which is a very inexpensive and mild reagent. Thiols were also shown to behave equally well under the same conditions. Chemoselective protection of less hindered alcohols in the presence of bulkier homologues and phenols in the presence of alcohols was achieved using competitive experiments.

Modification of chrysanthemum odour and taste with chrysanthemol synthase induces strong dual resistance against cotton aphids

“…Chrysanthemol was identified with an authentic standard (Sigma, Saint Louis, MO). The standard of chrysanthemyl acetate was prepared by acetylation of chrysanthemol as described (Mojtahedi and Samadian, ). The chrysanthemol emission from transgenic plants was quantified based on calibration curves with the authentic standard.…”

Detection of bacteria using antimicrobial polymer derived via ring-opening metathesis (romp) pathway

“…The antimicrobial sustainability of samples coating on microscope slides was performed according to the literature. [44] The polymer coated glass surface were challenged with E.coli and S. aureus at a concentration of about and the plates were incubated for 24 h at 37 °C and counted for colonyforming units. In the study, 25 mm diameter empty glass material (NC) and solvent (DMSO) coated glass material (SC) used as control samples.…”

Multiscale modelling investigation of wood modification with acetic anhydride

“…On the other hand, some mixed reviews have been proposed for the reactivity of the hydroxyl group in cellulose that all hydroxyl groups participate and convert into cellulose acetate. [51][52][53][54][55]…”
