Abstract
A double acceptor-activated cycloalkene 1 reacts in an FeCl3 . 6 H2O c atalysed Michael reaction surprisingly as a donor. The constitution of the product 2 results from a reaction of 1 in the gamma-position, thu s the Michael reaction is vinylogous with respect to the donor. A taut omerism between the enone 1 and the dienol 4 is found to be a precondi tion for this reactivity.
