چکیده
A new route to α-alkyl-α-fluoromethylenebisphosphonates, 2 has been developed starting from commercially available tetraethyl fluoromethylenebisphosphonate (1), and alkyl halides using either caesium carbonate in DMF or sodium dimsyl. De-esterification of 2 provided biologically important α-alkyl-α-fluoromethylenebisphosphonic acid, 3, while alkoxide-induced carbon-phosphorus bond cleavage of 2 gave α-fluorophosphonates, 4, which are useful synthons in organic synthesis.

Iridium-catalyzed selective α-methylation of ketones with methanol.
Iridium-catalyzed selective α-dimethylation and α-methylation of ketones or phenylacetonitriles, using methanol as the methylating agent, were achieved. In addition, three-component cross α-methyl-alkylation was successfully performed using methyl ketones with methanol and primary alcohols with long-chain alkyl groups. This method provides a very convenient direct route to α-methylated ketones,...
متن کاملPolyimide foams derived from a high Tg polyimide with grafted poly(α- methylstyrene)
A new route to high-Tg, thermally stable polyimide foams has been developed. Foams were prepared by casting microphase-separated graft copolymers comprising a thermally stable main chain, polyimide, and a thermally labile graft, poly(α-methylstyrene). The copolymer compositions were designed so that the thermally labile block would be the dispersed phase. This can unzip to its monomer upon heat...
متن کاملA new facile route to synthesize thieno[3,2-e][1,2,4]triazolo[4,3-c]pyrimidine derivatives
A new facile route for synthesis of 3- (aryl) -8, 9- di (alkyl) thieno [3,2-e] [1,2,4] triazolo pyrimidines derivative from the same starting material, 2- amino - 4,5 -di (alkyl) thiophene-3- carboxamide, has been developed through heterocyclization of the corresponding arylidene-hydrazino -5,6 -di (alkyl) thieno [2,3-d] pyrimidine under refluxing condition with acetic anhydride followed by air...
متن کاملCatalytic asymmetric synthesis of secondary nitriles via stereoconvergent Negishi arylations and alkenylations of racemic α-bromonitriles.
The first method for the stereoconvergent cross-coupling of racemic α-halonitriles is described, specifically, nickel-catalyzed Negishi arylations and alkenylations that furnish an array of enantioenriched α-arylnitriles and allylic nitriles, respectively. Noteworthy features of this investigation include: the highly enantioselective synthesis of α-alkyl-α-aryl nitriles that bear secondary α-al...
متن کاملLow Temperature Synthesis of α-Fe2O3 Nano-rods Using Simple Chemical Route
Iron oxide (Fe2O3) is widely used as a catalyst, pigment and gas sensitive material. In this article, α-Fe2O3 nano-rods were first synthesized via a simple chemical method using iron(III) nitrate 9- hydrate (Fe(NO3)3.9H2O) as precursor. XRD pattern showed that the iron oxide nanoparticles exhibited alpha-Fe2O3 (hematite) structure in nanocrystals. The single-phase α- Fe2O3 nano-rods were prepa...
