Nitrogen-15 NMR evidence for the structures ofN-9-H-Xanthen-9-yl- andN,N′-Di-9H-xanthen-9-yl-ureas
摘要:
AbstractA 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 15N NMR and other spectroscopic techniques. A series of 13C and 15N labeled urea derivatives has been prepared and the utility of their 13C and 15N chemical shifts and coupling constants in the structural analysis of urea derivatives has been investigated.

Detection reagent is formed by reacting a catalyst and xanthydrol. The catalyst includes an active component loaded on a support, wherein the active component includes Pt, Ru, Rh, or a combination thereof, and the support includes carbon material, silica, alumina, or calcium carbonate. The detection reagent can be used to detect the primary amide compound.
