Reaction of α-trifluoromethyl, α-cyano, and α-ethoxycarbonyl alkenyl sulfones with ethyl isocyanoacetate in the presence of a base gave 4- substituted pyrrole-2-carboxylates in moderate to good yields.
Reactivity of β-(trifluoromethyl) acroleins towards primary alkyl (or aryl) amines: synthesis of trifluoromethyl)-1-aza-1,3-dienes and secondary (trifluoromethyl) allylamines

Vilsmeier's reaction on trifluoroketones leads to β-chloro-β(trifluoromethyl)acroleins.The addition of primary alkyl- or aryl-amines to these acroleins leads in all cases to the formation of stable (trifluoromethyl)-1-aza-1,3-dienes which can be transform
