Reaction Steps

Part A. Employing methods similar to Example 1 Part A but using 4-cyano benzaldehyde (1.80 gm, 13.8 mmol) and 4-acetyl benzonitrile (1.0 gm, 6.89 mmol), 4-[3-(4-cyanophenyl)-1-oxo-2-propenyl]benzonitrile was isolated as a pale yellow powder, 0.4 gm (20%) MS 259(M+H)+ 1 H NMR (CDCl3): 7.78(d, 2H), 7.6(t, 1H), 7.5-7.0(m, 7H).
