Methoxymethyl Triphenyl Phosphonium Chloride
Wittig reagent precursor for one-carbon aldehyde homologation and stereoselective alkene synthesis.
Methoxymethyl triphenyl phosphonium chloride is a versatile phosphonium salt used extensively in organic synthesis as a Wittig reagent for carbonyl homologation. Reaction with aldehydes and ketones generates methoxyalkenes (enol ethers) that hydrolyze directly to the homologated aldehydes. It is an essential reagent in the total synthesis of natural products, pharmaceuticals and fine chemicals. Assay and packaging confirmed per enquiry.
