Lithium dicyclohexylamide
Lithium dicyclohexylamide (CAS: 4111-55-1) is a strong, non-nucleophilic organic base with the linear formula (C6H11)2NLi. Its molecular weight is 187.25 g/mol. This compound is highly reactive and pyrophoric, requiring careful handling. It is primarily utilised as a synthetic reagent in organic chemistry for deprotonation reactions where a powerful, sterically hindered base is needed to avoid unwanted nucleophilic attack.
Deprotonation Agent
Lithium dicyclohexylamide serves as an effective base for deprotonating weakly acidic compounds in organic synthesis. Its bulky nature minimises nucleophilic side reactions, making it suitable for complex transformations.
Organic Synthesis
This reagent is employed in various organic synthetic pathways, including the formation of carbanions and other reactive intermediates. Its strong basicity facilitates reactions that require significant proton abstraction.
Preparation of Organometallic Compounds
It can be used in the synthesis of specific organometallic reagents and intermediates. The lithium counterion is key in many such preparations.
