Melamine trisulfonic acid (MTSA) is utilized as a highly efficient catalyst for the solvent-free condensation reaction of 2-naphthol (2 eq.) with arylaldehydes (1 eq.) under conventional thermal as well as microwave conditions to give the d

The enhanced chemiluminescence (CL) reaction of the luminol±H2O2±horseradish peroxidase (HRP) system with immobilized HRP using microencapsulation in a sol±gel matrix has been used to develop a biosensor for p-iodophenol, p-coumaric acid, 2-naphthol and hydrogen peroxide. The detection limits obtained for p-iodophenol, p-coumaric acid and 2-naphthol were 0.83 mM, 15 and 48 nM, respectively. Dir...

In the title compound, C(23)H(25)NO, the dihedral angle between the naphthyl-ene ring system and the benzene ring is 78.17 (10)°. The mol-ecular conformation is stabilized by a strong intra-molecular O-H⋯N hydrogen bond.

OBJECTIVE To determine the transfer of 2-naphthol (2-NPH) in fullterm human placental tissues. METHODS Six placentas were studied. The ex-vivo dual closed-loop human placental cotyledon perfusion model was used. 2-NPH was added to the perfusate in the maternal compartment. Samples were obtained from the maternal and fetal up to 360 min measuring. RESULTS The mean fetal weight was 2880 ± 304...

The title Schiff base compound, C(16)H(14)N(2)O(2), has been synthesized by the reaction of 5-amino-3,4-dimethyl-isoxazole and 2-hydr-oxy-1-naphthaldehyde. The dihedral angle between the isoxazole ring and the napthyl ring system is 3.29 (7)°. The mol-ecule adopts an E configuration about the central C=N double bond. Intra-molecular O-H⋯N hydrogen bonding generates an S(6) ring motif. In the cr...

Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields. 

In this paper, the strength and kinetics of two charge-transfer complexes, naphthol-methylviologen and pyrene-methylviologen, are studied using dynamic force spectroscopy. The dissociation rates indicate an enhanced stability of the pyrene-methylviologen complex, which agrees with its higher thermodynamic stability compared to naphthol-methylviologen complex.
