Alkylidenecyclopropanes readily convert into cyclobutene derivatives on treatment with catalytic amounts of PtCl 2 . The reaction is strongly accelerated when performed under an atmosphere of CO (1 atm). The resulting cyclobutenes are isolated in good to...
Highly chemoselective direct reduction of primary, secondary, and tertiary amides to alcohols using SmI 2 /amine/H 2 O is reported. The reaction proceeds with C–N bond cleavage in the carbinolamine intermediate, shows excellent functional group tolerance, and...

The syntheses and X-ray diffraction structures of water soluble copper( II ) compounds containing the Schiff base ligand 2-(2-pyridylmethyleneamino)benzenesulfonate (L − ),viz. the dinuclear bis-μ 1,1 -azido [CuL(μ 1,1 -N 3 )] 2 ( 1 ) and bis-μ ...
With the activation of P(OEt) 3 and I 2 , carboxylic acids can smoothly react with various primary and secondary amines, affording a series of amides, including peptides without racemization. 31 P NMR spectroscopy studies showed that carboxylic...
The first total synthesis of spirobacillene A, an indole alkaloid isolated from Lysinibacillus fusiformis, is reported. A Lewis acid mediated spirocyclization of an anisole derivative onto a tethered ynone was used as a key step, drawing inspiration from a...
The effectiveness of immobilization of functionalized carbon nanotubes into chitosan using different cross-linking agents has been evaluated. The cross-linkers used were glyoxal (GO), glutaraldehyde (GA), epichlorohydrin (ECH), and...
We developed a series of nonchelated monodentate benzimidazole nickel complexes, bis[2-(2,6-difluorophenyl)-1H-benzimidazole]nickel(II) dibromide (1), bis[1-(2,6-difluorobenzyl)-2-(2,6-difluorophenyl)-1H-benzimidazole]nickel(II) dibromide (2),...

A convenient route to the enantiomers of 4-TIPS-3-butyn-2-ol of >95% enantiomeric purity by reduction of the ynone precursor 4 with the Noyori N-tosyl-1,2-diphenylethylenediamineruthenium cymene catalyst is described. The mesylate derivative of the (S)...

A novel entry to the synthesis of diazoacetates is disclosed. A variety of diazoacetates were synthesized from the corresponding bromoacetates by treatment with N,N‘-ditosylhydrazine in moderate to high yields. Ease of operation with the stable crystalline...
A computational and conceptual density-functional study has been performed on various [3 + 1] complexes of both Re(V) and Tc(V). The fully optimized complexes chloro(3-thiapentane-1,5-dithiolato)oxorhenium(V) and...
