What are some reported methods for the synthesis of DBU phenol salt?
The synthesis of DBU phenol salt, also known as 1,8-diazabicyclo[5.4.0]undec-7-ene phenolate, can be achieved through various methods. Here are some reported methods for its synthesis: Direct Salt Formation: The simplest method involves the direct reaction of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) with a phenol in a suitable solvent to form the phenolate salt. Typically, the phenol is added
