Two examples of N-aryloxy-β-diketiminate dianions (11a, b) have been synthesized on a multigram scale, in four steps, from commercially available chemicals. The synthetic scheme relies on the sequential addition of 2, 6-diisopropylaniline and 2-amino-4-tert-butylphenol (1a)(or 2-amino-4, 6-di-tert-butylphenol (1b)) to acetylacetone, using Et3OBF4 as an activation reagent. Both the nature of the activation reagent and the order of addition of the ...
