Application:	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.
Other Notes:	The article number 271012-4X2L will be discontinued. Please order the single bottle 271012-2L which is physically identical with the same exact specifications.
