This boronate ester features a sterically shielded tetramethyl-1,3,2-dioxaborolane core paired with a 3,3-dimethylbutenyl substituent, delivering enhanced stability and ease of handling. The electron-rich boron center enables efficient coupling in Suzuki-Miyaura reactions under mild conditions, while the bulky dimethyl groups suppress protodeboronation. This combination ensures high functional group tolerance and predictable reactivity in complex molecule assembly.
2-(3,3-Dimethyl-1-buten-1-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane serves as a stable, bench-ready boron building block for Suzuki-Miyaura cross-coupling reactions. Its sterically shielded dioxaborolane ring enhances air and moisture stability, while the terminal alkenyl group enables efficient coupling with aryl and vinyl halides under standard conditions. The reagent facilitates rapid access to substituted olefinic scaffolds with excellent functional group tolerance and straightforward purification.
