The strong influence of the metal (M) on the equilibrium 1 ‐M⇌ 2 ‐M (shown below) is clearly evident: it is far towards the 2 ‐M side with M = Li, whereas it is on the 1 ‐M side for M = ZnCl. The first crystal structure of a 2‐metalated oxazole, [ 3 ‐ZnCl⋅2 THF] 2 (below right), has been determined.
