Abstract

Carbodiimides have found a wide application in nucleic acid chemistry as effective condensing agenh3p4 Therefore, the mechanism of their reaction with various types of phosphorus acids attracted considerable attention. The reaction of dialkyl phosphates with dicyclohexylcarbodiimide (DCC) has been known since 1953 when they were shown by Khorana and Todd5 to give tetraalkyl pyrophosphates and dicyclohexylurea (DCU). The ...
