Boron trichloride
Boron trichloride (BCl3), CAS 10294-34-5, is a highly reactive Lewis acid and a valuable chemical reagent. With a molecular weight of 117.17 g/mol, this colourless gas is primarily employed in high-temperature synthesis processes for creating advanced materials, such as p-type semiconductor compounds. Its strong Lewis acidity also makes it useful in catalysis, particularly in promoting selectivity in organic reactions like the Diels-Alder reaction.
Synthesis of Layered Materials
Boron trichloride is used in the high-temperature synthesis of layered graphite-like materials that exhibit p-type semiconductor properties.
Catalysis in Organic Synthesis
Boronated aluminas derived from BCl3 act as highly acidic catalysts, promoting regio- and diastereoselectivity in organic reactions, including the Diels-Alder reaction.
Chemical Synthesis Reagent
As a versatile Lewis acid and strong chlorinating agent, BCl3 finds application in various chemical synthesis pathways.
