Prudent Practices for Disposal of Chemicals from Laboratories
Two of the compounds listed by Bretherick, sodium amide and potassium amide,
are common reagents that are relatively safe to use and dispose of if proper
precautions are taken. They may ignite or explode on heating or grinding in air, ...

Organic Chemistry: An Acid—Base Approach
If 1 is a very weak acid relative to 3, then water is a rather weak base in this
reaction—much weaker than sodium amide. If water is a weak base relative to
sodium amide, then Ka is large for the reaction with sodium amide and small for
the ...

Sodium Amides 2.3.1 Introduction The synthesis of sodium amide, NaNH2 (or
sodamide), by passing ammonia over heated sodium metal, was first reported
almost ...

Invitation to Organic Chemistry
Doing the same analysis, but using sodium hydroxide in place of sodium amide,
we find that if the stated reaction were to proceed, it would be written as follows:
C2H2 + NaOH (pKa 25) (PKa 15.7) Acetylene is the weaker acid of the two; ...

With a strong base such as sodium amide, both dehydrohalogenations oc— cur
readily. However, with weaker bases such as sodium hydroxide or potassium
hydroxide in ethanol, it is often possible to stop the reaction after the first dehy— ...

In each case, a third nitrogen atom must be introduced. With dinitrogen oxide, this
can be done by reacting dry N20 with sodium amide at 190 C: N2;6' + 'H2':NNa j±
NaN3 + H20. The product, sodium azide, is the sodium salt of hydrazoic acid.

Phosphorus Ylides: Chemistry and Applications in Organic ...
Sodium amide and, particularly, sodium bis(trimcthylsilyl)amide have proved very
good for the generation of salt-free ylides from the corresponding phosphonium
salts. Sodium bis(trimcthylsilyl)amide has the advantage of being easy to handle

... (meso) Given the ease of converting alkenes to dihaloalkanes and then to
alkynes, alkenes are versatile starting materials for the preparation of alkynes.
With a strong base such as sodium amide, both dehydrohalogenations occur
readily.

Concise Encyclopedia Chemistry
Replacement of a hydrogen atom in the NH3 molecule by a metal atom gives a
metal amide (e.g. sodium amide). Formamide and N, N-dimethylformamide are
common solvents; the latter is used as a formylating reagent in the Vilsmeier-
Haack ...
