(CHLOROMETHYL)TRIPHENYLPHOSPHONIUM CHLORIDE Usage And Synthesis
Chemical Properties
white to almost white fine crystalline powder
Uses
(Chloromethyl)triphenylphosphonium Chloride is a Wittig reagent.
Uses
Used for corrosion inhibition of iron
Reactant involved in:
- Acting as a potential electrophile
- Elimination reactions for the synthesis of linear alkynes
- Intramolecular nucleophilic vinylic substitution
- Homologation of aldehydes
- Endo-selective alkynol cycloisomerization
Preparation
(Chloromethyl)triphenylphosphonium chliride is available commercially (chloride or iodide salt) or synthetically from Triphenylphosphine and Chloroiodomethane.
Reactivity Profile
(Chloromethyl)triphenylphosphonium chliride is a precursor to the chloro-substituted ylide for Wittig reactions with aldehydes and ketones to form 1-chloroalkenes and, after elimination of HCl, terminal alkynes.
Precautions
For best results the anhydrous salt should be used. The ylide, formed from the salt and strong base, will react with air, water, or other acidic protons
