Product Name:(Triphenylphosphoranylidene)acetonitrile
English Name:(Triphenylphosphoranylidene)acetonitrile
CAS No.:16640-68-9
Aliases:Cyanomethylenetriphenylphosphorane, Triphenylphosphorane acetonitrile
Molecular Formula:C20H16NP
Physical Properties:White to off-white crystalline powder; melting point 185-190°C; soluble in dichloromethane and chloroform, slightly soluble in alcohols, insoluble in water; stable in air but light-sensitive; store sealed and protected from light.
Uses:This product is a stable phosphorane ylide (Wittig reagent), widely used in organic synthesis for converting aldehydes and ketones into α,β-unsaturated nitriles. It is also employed in the construction of carbon-carbon double bonds and the preparation of alkenenitrile compounds and pharmaceutical intermediates, offering mild reaction conditions and good selectivity.
Technical Specifications:
Appearance: white to off-white crystalline powder
Melting point: 185-190°C
Molecular weight: 301.32
Purity: ≥98%
Solubility: soluble in dichloromethane and chloroform, slightly soluble in methanol and ethanol
