Jul 29, 2011 · Although two equivalents of NaNH2 can result in some of the alkyne, it is more typical to use three equivalents because NaNH2 can deprotonate the acetylenic proton. This distinction is only for terminal alkynes.

Sodium amide can be prepared by the reaction of sodium with ammonia gas, [3] but it is usually prepared by the reaction in liquid ammonia using iron(III) nitrate as a catalyst.The reaction is fastest at the boiling point of the ammonia, c. −33 °C. An electride, [Na(NH 3) 6] + e −, is formed as a reaction intermediate. [4]2 Na + 2 NH 3 → 2 NaNH 2 + H 2. NaNH 2 …

氨基钠是一种无机化合物，化学式为NaNH 2 。 室温下纯品为白色固体，试剂常带金属铁而呈灰色。 氨基钠与水强烈反应，是有机合成中常用的强碱。

Question: For this reaction: 1. xs NaNH2 2. H2O Br Br Two sets of reagents are necessary for this transformation. What does the second reagent do? It is a strong base that is involved in the second beta-elimination. It is a weak acid that protonates the alkynide ion. It facilitates the tautomerization to form the alkyne product.
