The Stevens [1,2] rearrangement of acyl-stabilised ammoniumylides has been investigated with regard to stereoselectivity, intramolecularity and the formation of products in addition to the [1,2] rearrangementproduct. A detailed study of the effects of reaction conditions upon the rearrangement of the ylidederivedfrom the salt (13) has shown that the stereoselectivity (retention of the configuration
