The effects of electronic buttressing on the conformations of some orthodisubstituted benzenes

open access: yes, 1972
When one of a pair of substituents ortho to each other on a benzene ring is conjugated with an appropriate para substituent, it is pulled towards coplanarity with the aromatic ring and the other substituent has to take a greater share of the twisting ...

Synthesis of Some Novel 1,2-Disubstituted Benzimidazole-5-carboxylates via One-Pot Method Using Sodium Dithionite and Its Effect on N-Debenzylation

open access: yes, 2014
A series a novel of 1,2-disubstituted benzimidazole-5-carboxylates were prepared by the one-pot nitroreductive cyclization route using sodium dithionite, and its effect on N-debenzylation has been described.

Short Synthesis of Skeleton-Modified Cyclodextrin Derivatives with Unique Inclusion Ability

open access: yes, 2016
Skeleton-modified cyclodextrin (CD) derivatives, in which an α-(1,4)-glucosidic bond is converted into a β-(1,4)-glucosidic bond, were conveniently synthesized by cleavage of a single glucosidic bond in permethylated and 2,6-di-O-methylated α- and β-CDs ...

JSCS-3485 Original scientific paper Magnetic, spectrochemical and thermal properties of the

open access: yes, 2005
: Some physico-chemical properties of the 2-chloro-5-nitrobenzoates of Co(II), Ni(II) and Cu(II) were studied. The complexes were obtained as hydrates with a metal ion to ligand ratio of 1:2. All the complexes were polycrystalline compounds.

2,4,6-Trimethylpyridinium 4-nitrobenzoate–4-nitrobenzoic acid (1/1)

open access: yesActa Crystallographica Section E, 2011
The asymmetric unit of the title co-crystal, C8H12N+·C7H4NO4−·C7H5NO4, contains two cations, two anions and two neutral 4-nitrobenzoic acid molecules. In the crystal, O—H...O, N—H...O and C—H...O hydrogen bonds connect the ions and molecules, forming a three-dimensional network.

3-deoxy-2,5-DI-O-p-nitrobenzoyl-α-D-threo-pentofuranosyl bromide, a starting material for the synthesis of nucleosides

open access: yes, 1974
Hydrogenation (Raney nickel) of methyl 2,3-anhydro-α- and β-D-lyxo-furanoside (3 and 12) for 12 h at 60 60 lb.in.-2 afforded methyl 3-deoxy-α- and β-D-threo pentofuranoside (4 and 13). These were p-nitrobenzoylated to give the 2,5-di-p-nitrobenzoates (5b
