CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe reactivity of industrially relevant amines, 4,4′-methylenedianiline (MDA) and 2,4-diaminotoluene (TDA), towards methylphenylcarbonate (MPC), in the presence of Ph2P(O)OH, has been investigated. Both MDA and TDA are catalytically and selectively converted into mono- and di-methylcarbamate esters. Under the relatively mild working conditions used, the formation of ureas and/or N-methyl derivatives is totally repressed. The full spectroscopic characterization of the compounds formed upon interaction of amines with Ph2P(O)OH is also reported. The methodology here described also holds for other mono- and di-amines, both aliphatic and aromatic.
