Description

This boronate ester features a 3-chloro-4-fluorophenyl moiety integrated into a stable, tetramethyl-substituted dioxaborolane framework. The electron-deficient aryl group enhances coupling efficiency in Suzuki-Miyaura reactions, while the steric protection around boron ensures high bench stability and moisture tolerance under standard conditions.

Application

2-(3-Chloro-4-fluorophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane serves as a stable, bench-ready boron building block for Suzuki-Miyaura cross-coupling reactions. The ortho-heteroaryl substitution pattern enables efficient coupling with diverse aryl and heteroaryl halides, while the tetramethyl-substituted dioxaborolane moiety offers enhanced stability and ease of purification. Functions reliably in standard catalytic conditions, facilitating rapid access to biaryl scaffolds common in pharmaceutical and agrochemical research.
