Activation of Urea as a Leaving Group in Substitution Reactions of Formamidine
Ureas. — The loss of the urea fragment is observed for the first time in the exchange
process of the formamidine urea (I) with amines like 5-amino-1-pentanol (II). The process is quite slow in nonpolar solvents (benzene), with the amidine of type (II) being
the major product. In a protic solvent or under solvent-free conditions the reaction is
faster (no yield given). — (DIAZ, D. D.; LEWIS, W. G.; FINN*, M. G.; Chem. Lett.
