一般說明

Iridium is a rare and dense transition metal that belongs to the platinum group of metals and is known for its remarkable physical and chemical properties. Iridium is used in high-temperature applications such as crucibles for crystal growth and in devices that operate under extreme conditions due to its high melting point and stability at elevated temperatures. It is also used in electrical contacts and electrodes because of its excellent corrosion resistance and electrical conductivity. In addition, iridium is used as a catalyst in various organic reactions including hydrogenation, water splitting, C-C coupling, and olefin metathesis.

Compounds with carbon-boron bonds are versatile intermediates for building more complex molecules via the elaboration of the carbon-boron bonds into other carbon-element bonds. The synthesis of carbon-boron bonds by catalytic dehydrogenative borylation of carbon-hydrogen bonds with dialkoxyboranes (RO)2BH is particularly
