Piperidinium 3-hydroxy-2-naphthoate
The crystals of the title salt, C(5)H(12)N(+)·C(11)H(7)O(3) (-), were obtained from a methanol/water solution of 3-hydr-oxy-2-naphthoic acid and piperidine at room temperature. In the crystal structure, the piperidinium cations display a chair conformation and link with hydroxy-naphthoate anions via N-H⋯O and C-H⋯O hydrogen bonds. An intra-molecular O-H⋯O inter-action is also present.
متن کاملReactivity of α-hydroxy Acids towards Piperidinium Chlorochromate Oxidation
The kinetics of oxidations of α-hydroxy acids such as glycolic acid, lactic acid and mandelic acids with piperidiniumchlorochromate has been studied in aqueous acetic acid medium. The reaction order is one with respect to oxidant, substrate and fractional order with respect to hydrogen ion concentration. Decrease in dielectric constant of the medium increases the rate of reaction. No appreciabl...
متن کامل1-(3-Oxo-3-phenylpropyl)piperidinium chloride
In the title salt, C14H20NO(+)·Cl(-), the piperidine ring adopts a chair conformation. In the crystal, the cations and anions are linked by classical N-H⋯Cl hydrogen bond and weak C-H⋯Cl and C-H⋯O hydrogen bonds; the C-H⋯O hydrogen bonds exhibit R 2 (2)(14) ring motifs while the C-H⋯Cl hydrogen bonds link the mol-ecules into chains along the a-axis direction. π-π stacking is observed between pa...
متن کاملMethyl 1-bromo-2-naphthoate
In the mol-ecular structure of the title compound, C(12)H(9)BrO(2), the methoxy-carbonyl group is twisted by a dihedral angle of 29.8 (3)°with respect to the naphthalene ring system. An overlapped arrangement is observed between parallel naphthalene ring systems of adjacent mol-ecules, and the face-to-face distance of 3.590 (9) Å suggests there is π-π stacking in the crystal structure.
متن کاملAmmonium 1-hydroxy-2-naphthoate
The title compound, NH(4) (+)·C(11)H(7)O(3) (-), was obtained by slow evaporation of a 30% ammonia solution of 1-hydr-oxy-2-naphthoic acid. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds, forming layers parallel to the bc plane.
