Carbonylierung von Lithium‐monoalkylamiden zu N‐Lithio(alkyl)formamiden

Abstract: I 1 ) vollstiindig mit CO umzusetzen. Noch mehr ( 1 4 ) [Ausb. ca. 40x1 wird isoliert, wenn bei ca. 5°C (sonst nach AV) carbonyliert wird. Vermutlich reagiert ( I 2) mit CO zu einem kurzlebigen Addukt ( 1 6 ) , an das sich weiteres ( 1 2 ) rasch unter Bildung des von (14) abgeleiteten Dianions (1 7 j anlagert (Bildung des Dianions von ( 5 ) analog). Tatsachlich entsteht bei der Hydrolyse rnit D20rg1 und Aufarbeiten mit H 2 0 markiertes [D1]-( 14) ["].

“…Treating 42 with heavy water (i.e., D20) results in the formation of a deuterium-labeled N-formyl group. 36 An interesting rearrangement has been observed with the aminocarbonyllithium reagent generated from lithium ferf-butylamide.36 The preparation of IV-methyl-and 7V,iV-dimethylformamides has been described by Knifton,30 carried out over heterogeneous ruthenium "melt" catalysts, comprising one or more ruthenium oxide, salt, and complex species, dispersed in various phosphonium salts. This class of melt catalyst has been previously demonstrated to be particularly effective for the con- The suggested route for the formation of the trimethylamine, a principal byproduct, is shown in the above equation.…”
