Tetramethyldiborane
Tetramethyldiborane is a chemical compound with the formula (CH3)4B2H2. It is a member of the diborane family of compounds, which are characterized by the presence of two boron atoms and a varying number of hydrogen atoms and other substituents. Tetramethyldiborane is notable for its four methyl groups, which contribute to its unique chemical properties.
Structure and Bonding[edit | edit source]
Tetramethyldiborane adopts a structure similar to that of diborane, with two boron atoms linked by a bridging hydrogen atom. The four methyl groups are attached to the boron atoms, resulting in a highly symmetrical structure. The boron-hydrogen-boron bridge is a key feature of diborane and its derivatives, and is responsible for many of their unusual properties.
Synthesis[edit | edit source]
Tetramethyldiborane can be synthesized by the reaction of dimethylborane with hydrogen at high temperatures. This reaction is typically carried out in a sealed tube, and requires careful control of the reaction conditions to ensure the formation of the desired product.
Properties and Reactions[edit | edit source]
Tetramethyldiborane is a colorless liquid at room temperature, with a boiling point of approximately 60 degrees Celsius. It is highly reactive, and can undergo a variety of chemical reactions. For example, it can react with oxygen to form boron oxide and methane, or with water to produce boric acid and methane.
Applications[edit | edit source]
While tetramethyldiborane is primarily of interest for its chemical properties, it also has potential applications in the field of materials science. For example, it can be used as a precursor for the deposition of boron-containing films, which have potential uses in semiconductor technology.
Safety[edit | edit source]
Like many boron compounds, tetramethyldiborane is toxic and should be handled with care. It is also highly flammable, and should be stored away from sources of ignition.
