Abstract
Reaction of 2,3‐dihydro‐oxepin 1 with potassium amide in liquid ammonia yields, as revealed by NMR spectroscopy, the trans‐2,cis‐3,trans‐4,cis‐5 7‐oxaheptatrienyl anion 3, which is of fair configurational stability. The barriers for rotation in the oxaheptatrienyl anion are discussed.Keywords
