15 صفحه اولPlatinum-catalyzed cross-dehydrogenative coupling reaction in the absence of oxidant.
A third strategy for cross-dehydrogenative coupling reaction has been reported via platinum-catalyzed sp(3) C-H and sp(3) C-H coupling reaction in the absence of oxidant. Nitroalkanes as well as dialkyl malonate derivatives, beta-keto esters and malononitrile are active participants in this coupling reaction. Both cyclic and acyclic non-activated simple ketones are good reactants in this reaction.
متن کاملCross-dehydrogenative coupling for the intermolecular C–O bond formation
The present review summarizes primary publications on the cross-dehydrogenative C-O coupling, with special emphasis on the studies published after 2000. The starting compound, which donates a carbon atom for the formation of a new C-O bond, is called the CH-reagent or the C-reagent, and the compound, an oxygen atom of which is involved in the new bond, is called the OH-reagent or the O-reagent....
متن کاملA chemoselective α-aminoxylation of aryl ketones: a cross dehydrogenative coupling reaction catalysed by Bu4NI.
Tetrabutyl ammonium iodide (TBAI) catalyzed α-aminoxylation of ketones using aq. TBHP as an oxidant has been accomplished. We have shown that the CDC (cross dehydrogenative coupling) reactions of ketones with N-hydroxyimidates such as N-hydroxysuccinimide (NHSI), N-hydroxyphthalimide (NHPI), N-hydroxybenzotriazole (HOBt) and 1-hydroxy-7-azabenzotriazole (HOAt) lead to the corresponding oxygenat...
متن کاملEnantioselective oxidative cross-dehydrogenative coupling of tertiary amines to aldehydes.
The direct oxidative cross-dehydrogenative coupling (CDC) of two C H bonds can be an efficient and relatively clean strategy in organic synthesis. Various sp C Hbonds, such as benzylic and allylic C H bonds, the a-C H bonds of amines and ethers, and the C H bonds of alkanes can be oxidized for direct reaction with carbon nucleophiles. Among these reactions, the oxidation of tertiary amines to g...
