allyl (triphenylphosphoranylidene)acetate - Introduction
Allyloxycarbonylmethylene triphenylphosphorane is an organic compound with the chemical formula (C6H5)3P = CH-CO-OCH(CH3)2, abbreviated as carbonylmethylene triphenylphosphine.
Nature:
Carbonylmethylene triphenylphosphine is a colorless liquid with an odor similar to alcohol. It has a relatively low boiling point (about 150 ℃ ~ 160 ℃) and a high ignition point (about 190 ℃). It is soluble in most organic solvents, such as ethanol, dimethylformamide and benzene.
Use:
Carbonylmethylene triphenylphosphine is an important organic synthesis intermediate, which has multiple functions in organic synthesis reactions. It can be used for the nucleophilic addition reaction of olefins, the reduction reaction of aldehydes and ketones, and the carbonylmethylenation reaction of oxoacetone. In addition, the compound can also be used in the preparation of organic synthesis catalysts and the field of organic synthesis research.
Preparation Method:
Carbonylmethylene triphenylphosphine can be prepared by the reaction of phosphated methylene triphenylphosphine ((C6H5)3P = CH2) with oxoacetone (CH3COCOCH3). The reaction is generally carried out under an inert atmosphere and is promoted by heating.
Safety Information:
Carbonylmethylene triphenylphosphine is less toxic, but care should still be taken to prevent its contact with eyes, skin and administration. Wear appropriate protective gloves and eye protection during operation. In addition, care should be taken to avoid contact with substances such as strong oxidants, strong acids or strong bases to avoid dangerous reactions.
When using this compound, please strictly abide by the operating procedures of the chemical laboratory and operate under the guidance of professionals.
