illustri della cultura, della scienza, della politica,
testimoni della secolare capacità che l’Università di Padova ebbe – dal Duecento in avanti – di attrarre scolari da ogni dove. Il Volume sintetizza la loro storia personale (F. Piovan) e ricostruisce tempi e modi della decisione di collocare i loro ritratti (eseguiti da Gian Giacomo Dal Forno) nella Sala dei Quaranta, durante i lavori di riqualificazione del Bo, presieduti e coordinati da Carlo Anti e Gio Ponti, fra anni Trenta e Quaranta del Novecento (M. Nezzo)
“Carbomethoxylating reactivity of methyl phenyl carbonate towards aromatic amines in the presence of Group 3 metal (Sc, La) triflate catalysts”
No full textMethyl phenyl carbonate (MPC) has been investigated as a carbomethoxylating agent of aromatic amines in the presence of group 3 metal
(Sc or La) triflate catalysts. Under mild conditions (363 K), both Sc(OTf)3 and La(OTf)3 (OTf = O3SCF3) can promote the carbamation
of aniline and a few industrially relevant aromatic diamines, such as 4,4-methylenedianiline (MDA) and 2,4-diaminotoluene (TDA), with
MPC. Carbamate yield and selectivity are markedly affected by the experimental conditions (temperature, reaction medium, nature of the
metal center). Sc(OTf)3 is a more effective and selective carbamation catalyst than La(OTf)3. Ad hoc experiments have shown that, in the
presence of the M(OTf)3 (M = Sc, La) catalysts, MPC is not only more reactive but also a more selective carbomethoxylating agent than
dimethyl carbonate (DMC)
