The first examples of a Pd-catalyzed carbonylation of aryl boronic acids with sp3 carbon partners are presented. Various boronic acids were shown to react with 1,3-diesters and 1,3-diketones to afford structurally unique carbonyl compounds. By

(Chemical Equation Presented) A recyclable, convenient, and efficient catalytic system for C-acylation of 1,3-dicarbonyl compounds and malononitrile with acid chlorides has been developed, giving moderate to excellent yields under mild conditions. This is the first catalytic example of such reactions. In addition, by applying this protocol as the key step, 3,5-disubstituted-1H- pyrazole-4-carboxylate can easily be synthesized in high yields in a one-pot procedure.

Acidity constants and enol contents of ethyl benzoylmalonate and its para derivatives (CH3O, CH3, Cl, CN, NO2) were determined in 75 vol.percent ethanol-water solutions.Acidity constants of keto and enol forms were calculated and correlated with substituents constants ?p.IR spectra and enol contents were also determined in CCl4 solutions.
