Organostannanes are organic compounds that contain carbon-tin bonds, specifically featuring a tin atom bonded to one or more carbon atoms. They are part of a broader class of organometallic compounds, which include metals bonded to organic groups. Organostannanes are often used in various chemical reactions, including as reagents in organic synthesis and as intermediates in the production of pharmaceuticals. These compounds are notable for their unique properties, such as their ability to participate in cross-coupling reactions, which are essential in forming carbon-carbon bonds. Their applications extend to materials science, where they can be used in the development of polymers and other advanced materials, showcasing their versatility in both industrial and research settings.
