Activation of Urea as a Leaving Group in Substitution Reactions of Formamidine Ureas

Activation of Urea as a Leaving Group in Substitution Reactions of Formamidine Ureas

The reactions of formamidine ureas with amines take different paths under protic vs. nonprotic conditions; loss of the urea fragment has been observed for the first time when protons are made available intra- or intermolecularly.
