Tributylphosphane-catalyzed condensation of alcohol and carboxylic acid with DCC directed toward rotaxane synthesis
Tributylphosphane (TBP) was found to act as an effective catalyst for direct condensation of carboxylic acid and alcohol with dicyclohexylcarbodiimide (DCC). Condensation using a DCC-TBP system was successfully applied in the preparation of rotaxanes.
