CAS 2136-75-6: 2-(Triphenylphosphoranylidene)acetaldehyde

Description: 2-(Triphenylphosphoranylidene)acetaldehyde, with the CAS number 2136-75-6, is an organic compound characterized by the presence of a phosphoranylidene group attached to an acetaldehyde moiety. This compound typically exhibits a yellow to orange color and is known for its stability under ambient conditions. It features a central carbonyl group, which is reactive and can participate in various chemical reactions, including nucleophilic additions. The triphenylphosphoranylidene moiety contributes to the compound's unique reactivity and can influence its electronic properties, making it a useful intermediate in organic synthesis. Additionally, this compound may exhibit interesting optical properties due to the presence of the aromatic triphenyl groups, which can also affect its solubility in organic solvents. Its applications may extend to areas such as catalysis and the development of new materials, particularly in the synthesis of complex organic molecules. As with many organophosphorus compounds, handling should be done with care due to potential toxicity and reactivity.
