Article abstract of DOI:10.1002/hlca.19830660402

The reactions of isocyanates with hydroxylamine give rise to several compounds according to the different conditions involved when starting with the primary reaction products, the hydroxy-ureas.The pure compounds have been isolated.An interesting reaction of N-phenyl-N'-phenylcarbamoyloxyurea with sodium hydroxide has been observed.This compound is converted to 3-hydroxy-1,5-diphenylbiuret under conditions described.
