Abstract: A series of new water soluble carbodiimides have been synthesized, their ability for ring-chain tautomerism being studied by IR spectroscopy. The rate constants of hydrolysis of the carbodiimides in the presence and in the absence of a phosphate donor, mononucleotide, have been measured. It is shown that intramolecular cyclyzation of carbodiimides inhibits their interaction with nucleophiles. For example the compound R—N=C=N—CH2—CH2—NH(CH3)2C1, forming a five-membered ring, is practically inert in the presence of nucleophiles.
