Synthesis and Structure of Geminally Activated 1-Nitro-4-phenylbuta-1,3-dienes

Аннотация

The condensation of cinnamaldehyde with nitro-substituted CH acids (ethyl nitroacetate, nitroacetone, nitroacetophenone, and nitroacetonitrile) afforded a series of geminally activated 1-nitro-4-phenylbuta- 1,3-dienes. Their structure was determined on the basis of a set of ¹H, ¹³C–{1H}, ¹⁵N NMR, and IR spectra.
