Af-methylpyrrolidone NMP

For example. Union Carbide claimed the addition of water to the final reaction mixture in Af-methylpyrrolidone (NMP) [28]. Under these conditions, phase separation took place and the Rh(TPPMS) (TPPMS = triphenylphosphine monosulfate) catalyst was completely transferred into the aqueous phase. [Pg.635]

In 2013, two back-to-back papers caught our attention. The papers by the groups of Bi [101a] and Lei [101b] captured our interest as they concerned the use of silver catalysts (AgjCOj, 10mol% in both cases, the only difference was that the former group used 1,4-dioxane as the solvent, and the latter Af-methylpyrrolidone (NMP)) (Scheme 9.35). [Pg.474]

Already in 1994, Tominaga and Sasaki found that those ruthenium catalysts that are active in hydroformylation, such as Ru3(CO)j 2> re also able to reduce CO2 to CO in the presence of bis(triphenylphosphine)iminium chloride ([PPN]C1) at a total pressure of about 78.5bar (Scheme 3.10) [22]. High temperatures were required below 100 °C no CO evolved. Solvents with donating properties, such as NMP (Af-methylpyrrolidone) or DMA (dimethyl acetamide), showed highest activities. [Pg.274]
