1,5-Diazabicyclo[4.3.0]non-5-ene CAS: 3001-72-7, commonly known as DBN, is a bicyclic amidine base widely used in organic synthesis and process chemistry. Owing to its strong basicity and low nucleophilicity, DBN is particularly effective in reactions where proton abstraction is required without competing nucleophilic side reactions.
DBN is frequently applied in elimination reactions, cyclizations, condensations, and transition-metal-catalyzed transformations. Its rigid bicyclic structure enhances basic strength while maintaining good solubility in common organic solvents, making it suitable for both laboratory-scale synthesis and industrial processes.
