Category Infos

: Thiophenes; Thiophene is a five-membered heterocyclic compound containing a sulfur heteroatom with the molecular formula C4H4S. Thiophene is aromatic and is very similar to benzene; electrophilic substitution reaction is easier than benzene, and it is mainly substituted at the 2-position. Thiophene ring system has certain stability to oxidant.

: Borates; 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.
