Direct synthesis of α,β-unsaturated nitriles in solid/liquid heterogeneous medium
Ladhar,El Gharbi
, p. 413 - 417 (1991)
α,β-unsaturated nitriles are obtained with high yields by condensation of diversely substituted aldehydes using nitriles in the presence of K2CO3. These basic active species avoids aldolisation generally observed in this type of reaction.
