Aniline-methanol mixed clusters are ionized by single photon vacuum ultraviolet (VUV, 118 nm) radiation with which absorption to an excited intermediate S(1) state is not required. Aniline ion (An(+)), a series of (An)(n)(+)-(CH(3)OH)(m) (n = 1, 2) cluster ions, and their hydrogenated cluster ions, (An)(n)(+)-(CH(3)OH)(m)H (n = 1, 2) are observed by mass spectrometry. Infrared (IR) absorption s...

The conformation of the N-H bond in the structure of the title compound (N3CPBA), C(13)H(10)ClNO, is anti to the meta chloro substituent in the aniline benzene ring, similar to that observed with respect to the ortho chloro substituent in N-(2-chloro-phen-yl)benzamide (N2CPBA) and meta chloro substituent in N-(3,4-dichloro-phen-yl)benzamide (N34DCPBA), but in contrast to the syn conformation ob...

electrical sensitivity of a boron nitride nanotube (bnnt) was examined toward aniline (c6h5nh2) molecule by using density functional theory (dft) calculations at the b3lyp/6-31g (d) level, and it was found that the adsorption energy (ead) of aniline on the pristine nanotubes is a bout -19.03kcal/mol. but when nanotube has been doped with si and al atomes, the adsorption energy of aniline molecu...

Fluorescence yield near-edge spectroscopy (FYNES) above the carbon K edge and temperature programmed reaction spectroscopy (TPRS) have been used as the methods for characterizing the reactivity and structure of adsorbed aniline and aniline derived species on the Ni(100) and Ni(111) surfaces over an extended range of temperatures and hydrogen pressures. The Ni(100) surface shows appreciably high...

Treatment of 2-methylphenols with chloro(diphenyl)-λ-iodane led to their regioselective dearomatizing 2-phenylation into cyclohexa-2,4-dienone derivatives via a proposed ligand coupling reaction. In the same vein of investigation, treatment of 2-methylanilines with the λ-iodane 2-iodoxybenzoic acid IBX reagent led to their regioselective dearomatization into previously undescribed ortho-quinol ...

The title compound, C(17)H(17)ClN(2)O(3)·0.5C(6)H(12), was prepared by the condensation reaction of 4-meth-oxy-3-(propanamido)-benzoic acid with 4-chloro-aniline. The Cl atom, the propionyl CH(3) group and the cyclo-hexyl CH(2) group are disordered over two sets of sites of equal occupancy in both mol-ecules. The cyclo-hexane solvent mol-ecule is disordered over two orientations which were mode...

The Schiff base complexes of Pb(II) and Sn(II) with bidentate (NO), [M(sal-An)2] (sal-An = aniline salicylideneiminato); tridentate (ONO), [M(sal-OAP)H2O)] (sal-OAP = orthoaminophenol salicylideneiminato); and tetradentate (N2O2), [M(sal-o-phdn)] (sal-o-phdn = N,N'-ophenylene bis(salicylideneiminato) have been synthesized. The infrared spectra were recorded and full assignments of all observed ...

In the title compound, C20H20N2O3, the central 2,5-di-hydro-1H-pyrrole ring [r.m.s. deviation = 0.014 (1) Å] is oriented at dihedral angles of 77.81 (6) and 25.33 (6)°, respectively, to the attached phenyl ring and the aniline phenyl ring. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, mol-ecules are linked through pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an ...

The title compound, C(18)H(16)NOP·C(3)H(8)O, was synthesized by the reduction of (3-nitro-phen-yl)diphenyl-phosphine oxide in the presence of 2-propanol as recrystallization solvent. There are two molecules in the asymmetric unit. Each P atom is tetra-coordinated by three C and one O atom from two phenyl fragments, one aniline group and one double-bonded O atom in a distorted tetra-hedral geome...

The title compound, C(17)H(12)N(2)O(3), was synthesized by the reaction of 2-hy-droxy-1-naphthaldehyde with 4-nitro-benzenamine. These condense to form the Schiff base, which crystallizes in the zwitterionic form. In the structure, the keto-amino tautomer has a fairly short intra-molecular N-H⋯O hydrogen bond between the 2-naphthalenone and amino groups, with electron delocalization. The mol-ec...
