Michaeladditions of compounds having acidic hydrogen (ketones, nitro derivatives, ethyl cyanacetate and ethyl malonate) on α,β unsaturated amides are carried out in the presence of the system CsF/Si(OCH3)4. The reaction takes place in heterogeneous medium without solvent. Final products are obtained (in good yields) without hydrolysis. Normal 1–4 addition products are obtained with tertiary α,β ethylenic
