Thus 500 ml. of commercial anhydrous liquid anunonia is introduced into the flask from a cylinder through an inlet tube. The liquid is stirred, and a 0.5-g. piece of potassium is removed from a container of kerosene, blotted with filter paper, and added. After the appearance of a blue color about 0.25 g. of ferric nitrate hydrate is added, followed by 0.5-g. pieces of potassium until 9 g. (0.23 mole) has been added. Discharge of the deep blue color after about 20 min. indicates complete conversion to potassium amide. In contrast to sodamide and lithium amide, which form suspensions in liquid ammonia, potassium amide appears to be mostly in solution, although the solutions are opaque and have been regarded by some workers as suspensions.

Heterocyclic structures analogous to the intermediate complex result from azinium derivatives and amines, hydroxide or alkoxides, or Grignard reagents from quinazoline and orgahometallics, cyanide, bisulfite, etc. from various heterocycles with amide ion, metal hydrides,or lithium alkyls from A-acylazinium compounds and cyanide ion (Reissert compounds) many other examples are known. Factors favorable to nucleophilic addition rather than substitution reactions have been discussed by Albert, who has studied examples of easy covalent hydration of heterocycles.
