Abstract:The Wittig Reaction is a nucleophilic addition in which an alkene is formed as a product. Both the E and Z isomers of the alkene result. Substituents on the aromatic aldehyde affect the E/Z ratio of products that form. In this experiment‚ a nitro group was used as the substituent in the ortho‚ meta and para positions‚ with benzaldehyde as the control. Each of the four aldehydes reacted with (carbethoxymethylene) triphenylphosphorane to produce ethyl cinnamate‚ ethyl-3-(2-nitrophenyl)acrylate
