The ammonolysis of esters in liquid ammonia [PDF]

open access: yes, 2013
The rates of ammonolysis of alkyl benzoate and phenylacetate esters in liquid ammonia increase with the acidity of the leaving group alcohol and show relatively large Brønsted βlg values of −1.18 and −1.34, respectively, when plotted against the aqueous ...

Benzimidazolium 2-nitrobenzoate bis(2-nitrobenzoic acid)

open access: yesActa Crystallographica Section E Structure Reports Online, 2007
The title compound, C7H7N2+·C7H4NO4−·2C7H5NO4, consists of one benzimidazolium cation, one 2-nitro­benzoate anion and two 2-nitro­benzoic acid mol­ecules. These ions and mol­ecules build an infinite one-dimensional chain through hydrogen bonds.

Reactions of organoboranes with carbanions bearing three potential leaving groups: unusual processes, products and mechanisms [PDF]

open access: yes, 2016
Known reagents that transfer three alkyl groups of a trialkylborane intramolecularly to a single carbon atom lack features to influence stereochemistry. We have investigated four reagents of type LiCCl2X, where X might be amenable to variation.

Bacterial degradation of m-nitrobenzoic acid [PDF]

open access: yesApplied and Environmental Microbiology, 1995
Pseudomonas sp. strain JS51 grows on m-nitrobenzoate (m-NBA) with stoichiometric release of nitrite. m-NBA-grown cells oxidized m-NBA and protocatechuate but not 3-hydroxybenzoate, 4-hydroxy-3-nitrobenzoate, 4-nitrocatechol, and 1,2,4-benzenetriol. Protocatechuate accumulated transiently when succinate-grown cells were transferred to media containing m-

Crystal structure and Hirshfeld surface analysis of 2-{[2,8-bis(trifluoromethyl)quinolin-4-yl](hydroxy)methyl}piperidin-1-ium 2-hydroxy-2-phenylacetate hemihydrate [PDF]

open access: yes, 2016
The asymmetric unit of the title salt, C17H17F6N2O+·C8H7O3-·0.5H2O, comprises a pair of pseudo-enanti­omeric (i.e. related by a non-crystallographic centre of symmetry) piperidin-1-ium cations, two carboxyl­ate anions and a water mol­ecule of ...

Pd-catalyzed decarboxylative Heck vinylation of 2-nitrobenzoates in the presence of CuF2

open access: yesBeilstein Journal of Organic Chemistry, 2010
A new protocol for the decarboxylative Heck vinylation of benzoic acids is disclosed. In the presence of a catalyst system generated in situ from Pd(OAc)2 (2 mol %), CuF2 (2 equiv), and benzoquinone (0.5 equiv) in NMP, a wide range of olefins were ...

2-{[2,8-Bis(trifluoromethyl)quinolin-4-yl](hydroxy)methyl}piperidin-1-ium trichloroacetate: Crystal structure and Hirshfeld surface analysis [PDF]

open access: yes, 2018
The asymmetric unit of the centrosymmetric title salt, C17H17F6N2O+C2Cl3O2 , comprises a single ion-pair. The hydroxy-O and ammonium-N atoms lie to the same side of the cation, a disposition maintained by a charge-assisted ammonium-N—HO(hydroxy ...

Thiadiazoline- and Pyrazoline-Based Carboxamides and Carbothioamides: Synthesis and Inhibition against Nitric Oxide Synthase

open access: yesJournal of Chemistry, 2018
Two new families of pyrazoline and thiadiazoline heterocycles have been developed. Their inhibitory activities against two different isoforms of nitric oxide synthase (inducible and neuronal NOS) are reported.

Thermal Decomposition Mechanism of Silver Nitrobenzoates [PDF]

open access: yes, 2014
The infra-red spectra of silver salts of 3-mono-, 3,5-di-and 2,4,6-tri-nitro-benzoic acids have been recorded at elevated temperatures in a fabricated high temperature cell. The thermogravimetry i.e. TG analysis has also been carried out.
