Catalyzed by samarium triiodide (SmI3), substitution of acyl with N-acylbenzotriazoles for acetyl in acetoacetic esters and acetylacetone proceeds smoothly under neutral conditions in open air, affording the corresponding β-keto esters and β-diketones in good yields.

A cooperative indium(III)/silver(I) system for the synthesis of various five-membered heterocycles, including dihydrofurans, pyrroles, spirolactones, and spiroiminolactones, through the sequential oxidative coupling/annulation reaction of 1,3-dicarbonyl compounds with styrenes has been developed. Four different heterocyclic systems were successfully synthesized depending on the substitution pattern of the substrates using readily available starting materials. This system has the advantages of a broad substrate scope, moderate to good chemical yields, an operationally easy and simple procedure, and short reaction times. (Figure presented.) .
Keto-Enol Tautomerism in Micellar Solutions of Surfactants
Shtykov, S. N.,Parshina, E. V.
, p. 101 - 105 (2007/10/02)
Logarithms of the tautomeric equilibrium constants for benzoyl acetone (BA) and dibenzoyl methane (DBM) were found to be directly proportional to the reciprocal of the dielectric constant of water-ethanol solution and the logarithm of the concentration of surfactants (S) in aqueous micellar media.The effective values of the dielectric constant in the microenvironment of 1,3-diketones solubilized in micelles of S were estimated.BA and DBM were shown to be localized in the polar part of micelles in the vicinity of a boundary with the aqueous phase.
