The Schlenk equilibrium, which can be affected by the presence of dioxane, describes the stability of these compounds, whose synthesis can be improved by the addition of mercuric chloride amalgamates. They react with nitriles to form intermediate imine anions, and dry carbon dioxide can be bubbled through them to create carboxylic acids, which themselves do not form an addition product with these.
