boroncatalyzed
Boroncatalyzed refers to chemical processes in which boron-containing species serve as catalysts to accelerate reactions. In boron catalysis, boron acts primarily as a Lewis acid, coordinating to substrates such as carbonyls, imines, or alkenes to increase their electrophilicity or to stabilize key intermediates. Boron catalysts can be simple boron reagents such as boranes and boron trihalides, boronic acids and boronate esters, or more complex organoboron frameworks including chiral boron compounds. A prominent family is frustrated Lewis pairs (FLPs), in which a boron Lewis acid and a bulky Lewis base operate cooperatively to activate substrates without forming a stable adduct.
Mechanistically, boron catalysts often work by binding to a heteroatom or π-system, promoting bond activation, rearrangement,
Applications of boron catalysis span organic synthesis and materials chemistry. It is used to promote a variety
Advantages of boron catalysts include metal-free operation, tunable Lewis acidity through different boron substituents, and compatibility
