Used as a key reagent in organic synthesis, particularly in radical reactions. It serves as a source of cyclobutyl radicals when combined with transition metal catalysts or under photoredox conditions. This enables the cyclobutylation of aryl, heteroaryl, and alkenyl halides, which is valuable in medicinal chemistry for building strained ring systems. Its stability and ease of handling make it suitable for scalable transformations in drug discovery and development. Also employed in decarboxylative and dehalogenative couplings to introduce cyclobutane motifs into complex molecules, enhancing structural diversity.
