A new monoxanthen‒9‒yl derivative of urea has been synthesized and the structure of this product ( N ‒9 H ‒xanthen‒9‒ylurea) and that of the previously known N , N ′‒di‒9 H ‒xanthen‒9‒ylurea have been proved by 15 N NMR and other spectroscopic techniques. A series of 13 C and 15 N labeled urea derivatives has been prepared and the utility of their 13 C and 15 N chemical shifts and coupling constants in the structural analysis of urea derivatives has been investigated.
