Important organic reactions require the use of catalysts. The Friedel-Crafts reactions were discovered by Charles Friedel and James Mason Crafts in 1887. They are an essential catalytic process since they are widely applied in different areas such as fuels, cleaning, and pharmacological products. The reaction is usually carried out in the presence of Lewis acids or Brønsted acids in a homogeneous medium, with the nucleophilic aro Read More

This mini-review reports the current routes used for the production of dimethyl carbonate (DMC), a green and versatile methylating reactant widely used in organic synthesis. The use of DMC in methylation processes is also discussed. The main routes of DMC production, encompassing the reaction between phosgene and methanol and the oxidative carbonylation of methanol with CO and urea methanolysis, are summarised Read More

Trihaloisocyanuric acids [1,3,5-trihalo-1,3,5-triazine-2,4,6-(1H,3H,5H)-triones] are commercially available or easily prepared solids. They are highly reactive, stable, easily handled, and have an excellent atom economy, transferring up to three halogen atoms to organic substrates. In these regards, the present review summarizes their synthetic applications as safe and convenient reagents. Therefore, electrophilic halogenat Read More

Flow assurance encompasses the technical challenges of transporting hydrocarbon mixtures from the reservoir to the platform and refineries. Challenges in flow assurance include gas hydrate plugs, deposition of paraffin wax, asphaltenes, naphthenates, scale, and corrosion. Managing these deposits incurs high costs due to production interruptions and remediation operations like pigging, solvent injection, acid dissolutio Read More

An alternative to finding new drugs for the treatment of various diseases is the chemical modification of the structure of compounds of natural origin. Among them, naphthoquinones are very interesting candidates, as they are antibacterial, antifungal, antiparasitic, and anticancer agents. Naphthoquinones are redox compounds that can accept one or two electrons, generating reactive oxygen species in the cell and produc Read More
