Formylmethyltriphenylphosphonium chloride - Introduction
(formylmethyl)triphenylphosphonium chloride is an organic compound with the chemical formula [(C6H5)3PCH2]Cl and a molecular weight of 365.43g/mol. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
(formylmethyl)triphenylphosphonium chloride is a colorless to yellow crystalline powder. It is stable in air but decomposes when exposed to moisture. This compound is typical of phosphonium chloride salts in which phosphonium (Ph3P) is an organophosphine ligand. It is soluble in a variety of organic solvents, such as ether, methylene chloride and methanol.
Use:
(formylmethyl)triphenylphosphonium chloride are often used as formyl carrier in organic synthesis. It can be used to transfer formyl groups to other molecules, and is commonly used in the reduction of ketones, the carbonylation of thiols, and the deetherification of intramolecular phenols. In addition, it can also be used for the synthesis of organophosphorus compounds and organometallic complexes.
Preparation Method:
(formylmethyl)triphenylphosphonium chloride are generally prepared by reacting the phosphonium salt triphenylphosphonium chloride (Ph3PCl) with formaldehyde or acetaldehyde. The reaction conditions are generally carried out under an inert atmosphere.
Safety Information:
The use or operation (formylmethyl) of triphenylphosphonium chloride requires compliance with appropriate laboratory safety regulations. Since the compound is easily decomposed in a humid environment, it is preferably stored in a dry environment. It is irritating to the skin, eyes and mucous membranes and may be harmful to the respiratory tract. Appropriate personal protective measures should be taken during operation, such as wearing gloves, goggles and protective masks. When handling the compound, avoid inhaling its dust, avoid skin contact and eye contact. In the event of inadvertent exposure to the compound, immediately flush the affected area with plenty of water and seek medical help.
