Abstract:
β-Lithiooxyphosphonium ylides, generated in situ from aldehydes and methylenetriphenylphosphorane, react with halomethyl esters to form disubstituted allylic esters in good yields and with high Z-selectivity.

Aldehydes and Ketones to Alkenes: Wittig Reaction Mechanism
The reaction begins with the nucleophilic addition between a phosphorus ylide and the carbonyl compound. Due to its carbanionic character, phosphorus ylide acts as a strong nucleophile and attacks the electrophilic carbonyl group. This generates a charge-separated dipolar intermediate called betaine. The negatively charged oxygen atom and...
