Borates are classified as critical materials, they are the main source of boron and have a variety of industrial applications. Organic trifluoroborate is stable to heat, air and humidity, and is a very convenient crystalline boric acid compound. Since it has a tetra-coordinated boronic acid structure after the substitution of fluorine, it does not exhibit Lewis acidity and is stable to oxidation conditions. In addition, it can be regarded as the protector of boronic acid and boronic acid ester, which can be converted into each other. The compound can generally exist stably in organic solvents, but will decompose in protic solvents to liberate trivalent boron, so it can be directly used as a substrate for Suzuki coupling. The difference between trifluoroborate and boric acid is that it must exist in a monomeric form, so the equivalent weight can be closely controlled.
Triazole refers to a heterocyclic compound with the molecular formula C2H3N3, which has a five-membered ring consisting of two carbon atoms and three nitrogen atoms. Neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease already affect many people around the world, and these numbers are increasing rapidly. Treatment for these disorders is often aimed at relieving symptoms and has no cure. Research on new molecules is underway, and heterocyclic compounds have important pharmacological implications. Triazoles and tetrazoles are emerging as new molecules in this field.
Benzoheterocycles are heterocycles which are fused with a benzene ring. Coumarone, thianaphthene, benzopyridine, isoquinoline, and dibenzopyridine all belong to this class of compounds.
