(triphenylphosphoranylidene)acetonitrile - Introduction
Nature:
(triphenylphosphoranylidene)acetonitril is a colorless to pale yellow liquid. It has low vapor pressure and volatility at room temperature. This compound is hardly soluble in water, but soluble in organic solvents such as diethyl ether, dichloromethane, etc. It is sensitive to air and light and should be stored in a cool, dry place and away from fire and oxidants.
Use:
(triphenylphosphoranylidene)acetonitril has a wide range of uses. It can be used as a catalyst and reagent in organic synthesis, especially in Carbonylation and hydrogenation reactions. In addition, it can also be used for the preparation of organometallic compounds such as (triphenylphosphoranlylidene) acetonitril complexes and the like. The compounds can also be used as ligands in coordination chemistry studies.
Method:
(triphenylphosphoranylidene) The common preparation method of acetonitril is obtained by the reaction of phosphine and activator. A common preparation method is to react triphenylphosphine and butyl lithium to form lithium triphenylphosphine, and then react with methyl cyanide to obtain the target product (triphenylphosphoranlydene) acetontril.
Safety Information:
(triphenylphosphoranylidene)acetonitril is generally safer under normal use conditions, but the following points still need to be paid attention:
1. Should be away from the fire and oxidant, avoid contact with flammable.
2. Wear appropriate protective measures when using, such as chemical safety glasses, gloves and laboratory coats.
3. In use or storage, should strictly follow the safety procedures, keep good ventilation.
4. Avoid inhaling the vapor or dust of the compound, and avoid contact with skin and eyes. In case of accidental contact, flush immediately with plenty of water and seek medical help.
When using or handling this compound, make sure to follow proper laboratory safety practices and refer to specific safety data sheets and chemical labels.
