Allyltri-n-butyltin acts as an allylation reagent for aldehydes catalyzed by chiral Lewis acids and ytterbium(III) trifluoromethanesulfonate. It is also used to prepare homoallylic alcohols with trichloro-1,3,5-triazene. Further, it plays an important role for tetrakis(triphenylphosphine)palladium(0) catalyzed coupling reaction with iodoquinones and allyl acetates.
5-Chloro-2-methoxyphenylboronic acid serves as a versatile building block in Suzuki-Miyaura cross-coupling reactions, enabling efficient construction of biaryl scaffolds. The chloro group allows for subsequent functionalization via palladium-catalyzed coupling or nucleophilic substitution, while the methoxy substituent enhances solubility and modulates electronic properties. Bench-stable and readily purified by recrystallization, it facilitates reliable synthesis of complex aromatic architectures in medicinal chemistry and materials science applications.
