## Abstract A new method for preparation of enamides (__N__β(alkenβ1βyl) amides) by means of the βlongβdistance' migration of the double bond in unsaturated amides in the presence of [Fe(CO)~5~] is described. The method is shown to be particularly useful for the isomerization of __N__β(butβ3βenyl)a
## Abstract In Ο systems with localized double bonds, the switch from one localization pattern to another symmetryβequivalent one, and the corresponding changes in electron distribution are often considered to proceed __via__ a delocalized transition state of higher symmetry. We present a different
