A cheaper form of this reaction also bears the name of Horner, and uses a phosphite ester instead of a phosphine.
A cheaper form of this reaction also bears the name of Horner, and uses a phosphite ester instead of a phosphine. Triphenolphosphines tend to give the cis isomer, while trialkylphosphines, or any presence of groups that stabilize the ylide give the trans isomer. During its first step, the nucleophilic carbon from the ylide reagent adds to the electrophilic carbon in the polar carbonyl group, while the second step involves the decomposition of the intermediate carbon-phosphorus bond. FTP, identify this organic reaction, useful for producing alkenes.
