Borane-triphenylphosphine complex

Description:
Borane-triphenylphosphine complex, with the CAS number 2049-55-0, is a coordination compound formed between borane (BH3) and triphenylphosphine (PPh3). This complex is characterized by its ability to act as a Lewis acid due to the electron-deficient boron atom, which can accept electron pairs from Lewis bases. The triphenylphosphine ligand enhances the stability of the borane, allowing for easier handling and manipulation in synthetic applications. The complex is typically a white to yellow solid and is soluble in organic solvents such as dichloromethane and tetrahydrofuran. It is often used in organic synthesis, particularly in hydroboration reactions, where it facilitates the addition of boron to alkenes and alkynes. Additionally, the complex can serve as a source of boron in various chemical transformations, making it valuable in the preparation of organoboron compounds. Care should be taken when handling this compound, as it can be sensitive to moisture and air, leading to decomposition.
