In a process for the preparation of alkali metal hydride from the elements alkali metal and hydrogen, the improvement which comprises carrying out said reaction in an inert atmosphere in the presence of a catalyst of the formulas ##STR23## wherein Me represents an alkali metal, each X represents sulphur or oxygen, n represents a whole number from 3 to 20, L and L' represents a mono- or polyfunctional ether or amine, respectively, p and q are whole numbers from 0 to 4, R.sup.1, R.sup.2, R.sup.3, R.sup.4 are each hydrogen, alkyl, cycloalkyl, aralkyl or aryl moieties and/or two or more such moieties closed to form an aliphatic or aromatic ring system at no higher than room temperature.
In a process for the preparation of alkali metal nitride from the element alkali metal and nitrogen, the improvement which comprises carrying out said reaction in an inert atmosphere in the presence of a catalyst of the formulas ##STR24## wherein Me represents an alkali metal, each X represents sulphur or oxygen, n represents a whole number from 3 to 20, L and L' represents a mono- or polyfunctional ether or amine, respectively, p and q are whole numbers from 0 to 4, R.sup.1, R.sup.2, R.sup.3, R.sup.4 are each hydrogen, alkyl, cycloalkyl, aralkyl or aryl moieties and/or two or more such moieties closed to form an aliphatic or aromatic ring system at no higher than room temperature.
