Organoboranes are a class of chemical compounds that contain carbon-boron bonds. They typically consist of a boron atom bonded to one or more organic groups, which can include various hydrocarbons. These compounds are important in organic chemistry and are often used as intermediates in the synthesis of other organic molecules. One of the key features of organoboranes is their reactivity, particularly in cross-coupling reactions. They can participate in reactions that form carbon-carbon bonds, making them valuable in the development of pharmaceuticals and materials. Their unique properties also allow for the formation of organoborane derivatives, which can further expand their applications in chemical synthesis.
