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.
Pyrazoles are organic compounds of the general formula C3H3N2H. It is a five-membered heterocycle consisting of three carbon atoms and two adjacent nitrogen atoms. As an H-bond-donating heterocycle, pyrazole has been used as a more lipophilic and metabolically more stable bioisomer of phenol. Pyrazoles have attracted more and more attention due to their broad spectrum of action and strong efficacy.

Boronic acids and boronate esters are commonly used reagents in Suzuki–Miyaura coupling chemistry. Organoboron derivatives are common reagents for C–C bond formation, either through classical palladium-mediated transformations or through other newer coupling methods. Boronic esters and acids are potential intermediates in the manufacture of many active pharmaceutical ingredients (API).
