“Push‐pull” compounds 4 are obtained in good yields in an unusual way by addition of carboxamides 2 to the extremely reactive alkynyl trifluoromethyl sulfone 1 . A crucial feature of this reaction is the activation of the triple bond in 1 by the F 3 CSO 2 group. Dimethyl sulfoxide also adds spontaneously to 1 .
