Ragni, Roberta,Orselli, Enrico,Kottas, Gregg S.,Omar, Omar Hassan,Babudri, Francesco,Pedone, Adriana,Naso, Francesco,Farinola, Gianluca M.,De Cola, Luisa
experimental part, p. 136 - 148 (2009/06/18)
The synthesis and photophysical and electrochemical characterisation of new heteroleptic iridium complexes with electron-withdrawing sulfonyl groups and fluorine atoms bound to phenylpyridine ligands are reported. The emission energy of these materials st

Page/Page column 23, (2010/02/13)
Various compounds such as those having the formula I and XIV where the variables have the values described herein antagonize the vitamin D receptor and are useful in treating conditions such as asthma and in preparing medicaments for use in antagonizing the vitamin D receptor or treating conditions such as asthma

Fargeas, Valérie,Baalouch, Myriam,Metay, Estelle,Baffreau, Jer?me,Ménard, Delphine,Gosselin, Pascal,Bergé, Jean-Pascal,Barthomeuf, Chantal,Lebreton, Jacques
, p. 10359 - 10364 (2007/10/03)
A simple and efficient methodology to introduce an 1,3-diketone motif from various aldehyde precursors in three steps with good overall yields is described using β-ketosulphone 7 as masked equivalent of acetone. A three-step sequence was studied leading i
Autoxidation of Nonane and Decane: A Product Study
Goosen, Andre,Morgan, David H.
, p. 557 - 562 (2007/10/02)
The autoxidation of nonane and decane has been shown to occur in three stages.The initial stage leads to alkyl hydroperoxide formation and in the second stage the hydroperoxide decomposes to produce alcohols and ketones as major products.These studies sup
A new, simple, and general synthesis of 1,3-, 1,4- and 1,5-diketones from functionalized nitroalkanes
Ballini,Bartoli
, p. 965 - 967 (2007/10/02)
Herein is reported the utilization of protected nitro ketones, in the synthesis of 1,3-, 1,4-, and 1,5-diketones, by their condensation with aldehydes then conversion of the obtained conjugated nitroalkenes into monoprotected carbonyl derivatives which, by removal of the protecting group, gives diketones.
Synthesis of 1,3-Dicarbonyl Compounds by the Oxidation of 3-Hydroxycarbonyl Compounds with Corey-Kim Reagent
Katayama, Sadamu,Fukuda, Kinue,Watanabe, Toshio,Yamauchi, Masashige
, p. 178 - 183 (2007/10/02)
A new method for the preparation of various 1,3-dicarbonyl compounds is described.Oxidation of 3-hydroxycarbonyl compounds without substituent at C-2 position by the Corey-Kim reagent (N-chlorosuccinimide-dimethyl sulfide) afforded the stable dimethylsulfonium methylides, which on reductive desulfurization by zinc-acetic acid furnished the 1,3-dicarbonyl derivatives.On the other hand, the same treatment of 2-mono-, or 2,2-disubstituted 3-hydroxy-carbonyl compounds gave directly the corresponding 1,3-dicarbonyl analogous, respectively.
Chemical process for preparing 1,3 diketones
-
, (2008/06/13)
Novel (3',5'-dihydrocarbyl-4'-hydroxybenzyl)-1,3-diketones are prepared by reacting an N,N-dihydrocarbyl-2,6-dihydrocarbyl-4-aminomethylphenol with a 1,3-diketone in the presence of a basic substance. The products are useful as antioxidants.

Novel (3',5'-dihydrocarbyl-4'-hydroxybenzyl)-1,3-diketones are prepared by reacting an N,N-dihydrocarbyl-2,6-dihydrocarbyl-4-aminomethylphenol with a 1,3-diketone and an alkyl halide in the presence of an alkali or an alkaline earth metal hydride. The products are useful as antioxidants.
A NEW PREPARATIVE METHOD FOR 1,3-DICARBONYL COMPOUNDS BY THE REGIOSELECTIVE OXIDATION OF α,β-UNSATURATED CARBONYL COMPOUNDS, CATALYZED BY PdCl2 USING HYDROGENPEROXIDES AS THE REOXIDANT OF Pd0
Tsuji, Jiro,Nagashima, Hideo,Hori, Kimihiko
, p. 257 - 260 (2007/10/02)
α,β-Unsaturated esters and ketones are oxidized regioselectively to give β-keto esters and 1,3-diketones in good yields in aqueous acetic acid using Na2PdCl4 as the catalyst and t-butyl hydroperoxide or hydrogen peroxide as the reoxidant of Pd0.
