The use of carbonyl‐stabilized ammonium‐ and sulfonium ylides allows for the synthesis of highly‐functionalized trifluoroacetyl‐substituted cyclopropanes. It turned out that the diastereoselectivities strongly depend on the nature of the chosen ylide and the employed base. The products could be obtained in good yields under operationally simple conditions.
