Applicazioni

N,N-Dimethylacetamide may be used as a solvent in the following processes:
  • Palladium (II) acetate-butyldi-1-adamantylphosphine catalyzed arylation of 2-isobutylthiazole with chlorobenzene to form 5-phenyl-2-isobutylthiazole.
  • Synthesis of β-, γ-, and δ-metallo ester intermediates that can react with acid chlorides to form γ-, δ-, and ε-keto esters.
  • Synthesis of (R)-(-)-methyl 1,1′-binaphthyl-2,2′-diylphosphate that can be used as a precursor for preparing (R)-(+)-1,1′-binaphthalene-2,2′-diol.

Scale-Up Guide: Buchwald-Hartwig Amination Reaction

All of the preformed catalysts used in the kit are air and moisture stable complexes in their commercially available form. Once activated by base under the reaction conditions they become sensitive to air. To best enable scale-up success, the use of standard Schlenk technique is recommended.
