Iodine has been attracting much attention since its discovery in 1811. It is the weakest
oxidizer among the halogens and a poor electrophile that often needs the assistance of a …

In this work an optimization of the solvent-free acetylation of cellulose with acetic anhydride
under microwave heating with iodine as a catalyst was performed. The optimized …

Bacterial cellulose preserving the microfibrillar morphology was partially acetylated by the
solvent-free acetylation method using acetic anhydride in the presence of iodine as a …

An efficient TaBr5 (5–10mol%)-catalyzed Biginelli reaction under solvent-free conditions for
one-pot syntheses of 3, 4-dihydropyrimidin-2-(1H)-ones (DHPMs) and their thione analogs …

In vertebrates, thyroid hormones (THs, thyroxine, and triiodothyronine) are critical cell
signaling molecules. THs regulate and coordinate physiology within and between cells …

A heterogeneous cobalt(II) Salen complex as an efficient and reusable catalyst for acetylation
of alcohols and phenols - ScienceDirect Skip to main contentSkip to article Elsevier logo …

Aluminium triflate (0.01–0.1 mol%) was found to be an efficient catalyst for the acylation of
alcohols, phenols, thiols and sugars with acetic anhydride in high yields under solvent-free …

A novel photochromic azobenzene-based surfactant was described for organic chemistry in
water. The molecule 4-butylazobenzyl-4′-triazologlucuronic acid sodium salt thus …
