Used as a key reagent in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions. It serves as a boron-based coupling partner to introduce alkenyl groups, such as the cyclopentylidenemethyl moiety, enabling the formation of carbon-carbon bonds in pharmaceuticals, agrochemicals, and advanced materials. The cyclopentylidene moiety allows access to strained or conformationally restricted structures, which are valuable in drug design for enhancing metabolic stability and target selectivity. Its stability and reactivity profile make it suitable for late-stage functionalization in complex molecule synthesis.
