skf45359 - Introduction
Benzoylmethylenetriphenylphosphorane(Benzoylmethylenetriphenylphosphorane) is an organic compound whose molecular formula is C27H21OP. The following is a description of its nature, use, preparation and safety information:
Nature:
Benzoylmethylenetriphenylphosphorane is a colorless to light yellow crystal. It can be dissolved in organic solvents such as ethanol and dimethylformamide at room temperature, but it is insoluble in water. It is a compound with unique electronic properties in a spatial configuration.
Use:
Benzoylmethylenetriphenylphosphorane is often used as a reaction reagent in organic synthesis, including Horner-Wadsworth-Emmons reaction and Wittig reaction. It can react with aldehydes or ketones to form olefinic compounds containing double bonds. In addition, it can also be used in the synthesis of drugs, biologically active compounds and other key steps in organic synthesis.
Preparation Method:
The preparation method of Benzoylmethylenetriphenylphosphorane is usually obtained by reacting benzoylformic acid thioester with triphenylphosphine bromide. The reaction is generally carried out in an anhydrous organic solvent such as dimethylformamide or tetrahydrofuran. After completion of the reaction, the product can be purified by crystallization or column chromatography.
Safety Information:
Benzoylmethylenetriphenylphosphorane are generally relatively safe under normal conditions of use. However, as an organic compound, it still has a certain potential danger. Care should be taken to follow basic laboratory safety practices, such as wearing appropriate protective equipment (such as gloves and glasses) to prevent contact with skin and eyes. In addition, in contact with other chemicals, especially strong oxidants and combustibles, special care should be taken to prevent unexpected reactions and accidents. Handle and store in a well-ventilated place and avoid prolonged contact with air, water and moisture.
