Methods and Examples of the Performance of the Reaction,f addition of the reagents — the alkali metal, the ammonia, and the alcohol — and also by the presence or absence of supplementary solvents. Since the reaction is carried out in liquid ammonia, its temperature range is determined by the boiling and solidification points of ammonia (from -34°C to -80
