The electron impact and chemical ionization mass spectra of a series of N,N,'-diaryl ureas have been compared. The electron impact mass spectra indicate rearrangements leading to two pairs of aromatic amines and isocyanates, either as ions or molecdes. The chemical ionization mass spectra showed the formation of protonated amines and isocyanates via rearrangement.

Untersuchungen zeigen, daß die Oxidation der Alkylhydrazine (IV) mit Jod in Gegenwart von Basen üblicherweise zu einem Gemisch der entsprechenden Alkyljodide (I), Alkane (II) und Alkene (III) und in wäß‐ rigem Medium außerdem zu Alkoholen (V) führt, deren relative Mengen von der Struktur der Alkylhydrazine, dem Lösungsmittel und denverwendeten Basen abhängig sind.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
