Table 1. Catalyst Screening for Hydrogenation of N2Oa,b,c.
All the reactions were conducted in a 90 mL Fisher-Porter tube using 13 mmol of H2 and N2O in 5 mL THF.
All the complexes except 13 were freshly prepared from the corresponding aromatized (pincer)RuH(Cl)(L) with 1 equiv tBuOK in THF and used directly in the reactions. Complex 13 was obtained similarly using KHMDS as base.
The TONs are based on the generated H2O as measured by 1H NMR of the reaction mixture using mesitylene as internal standard (see SI for details).
