Substituents on Aromatic Aldehydes and How They Affect E/Z Selectivity in the Wittig Reaction
up is substituted in the ortho, meta, and para positions, and benzaldehyde serves as a control. The ylide used is (carbethoxymethylene) triphenylphosphorane. Through the utilization of NMR spectroscop ... The starting materials for a Wittig Reaction are a compound with a carbonyl group and a phosphorus ylide. The carbon of the carbonyl is a strong electrophile because the oxygen pulls electron density ...
