Summary
m-Nitrobenzaldehyde, p-nitrobenzaldehyde, and o, o, p-trinitrobenzaldehyde were treated with cyanomethyl-enetriphenylphosphine and acetylmethylenetriphenylphosphine to yield the corresponding nitriles of cinnamic acid and benzalacetones, respectively, containing a nitro group in the benzene nucleus.
