In many instances the practicality of the methods have limitations such as harsh reaction conditions, high temperature, strong bases, requirement of precious metal combinations. Therefore, the development of convenient, practical methods for the hydration of nitriles to amides under transition metal-free conditions still holds its relevance.

Strong base. OTHER SETS BY THIS CREATOR Heterocyclic bases such as pyridine and quinoline and their derivatives react with metal amides to yield amino derivatives. For example, pyridine is converted to 2‐aminopyridine by the action of sodium amide; an intermediate metal derivative is formed, and this is hydrolyzed to the free amine. 2013-07-15 Therefore, amides don't have as clearly noticeable acid–base properties in water. This relative lack of basicity is explained by the withdrawing of electrons from the amine by the carbonyl. On the other hand, amides are much stronger bases than carboxylic acids, esters, aldehydes, and ketones (their conjugate acids' pK a s are between −6 and −10).

The transition metal catalysed hydroamination is an important reaction in synthetic chemistry. 1 The related catalytic reaction of alkene derivatives with lithium amides has been widely investigated (Scheme 1). 2 Major limitations remain for the use of polar lithium metal amides for alkene addition reactions as uncontrollable polymerization is often an occurring reaction. 3 Presumably, this is
