Sarkhoon gas plant, located in south of Iran, has been installed to removal H2S contained in a high pressure natural gas stream. The solvent used for the H2S removal from gaseous stream is 34% by weight (wt%) Di-ethanol amine (DEA) solutions. Due to increasing concentration of heat stable salt (HSS) in solvent, corrosivity of amine solution had been increased. Reports indicated that there was c...

In the title compound, C(12)H(12)N(2)O, the dihedral angle between the planes of the pyridine and phenyl rings plane is 35.94 (12)°. In the crystal structure, centrosymmetrically related mol-ecules are linked by a pair of N-H⋯N hydrogen bonds, forming a dimer with an R(2) (2)(8) ring motif. In addition, there is an intra-molecular N-H⋯O inter-action.

In the title mol-ecule, C6H8N2, the endocyclic angles are in the range 118.43 (9)-122.65 (10)°. The mol-ecular skeleton is planar (r.m.s. deviation = 0.007 Å). One of the two amino H atoms is involved in an N-H⋯N hydrogen bond, forming an inversion dimer, while the other amino H atom participates in N-H⋯π inter-actions between the dimers, forming layers parallel to (100).

The title compound, C(7)H(10)N(2)O, crystallizes with two independent mol-ecules in the asymmetric unit. The bond lengths and angles in the mol-ecules are within normal ranges. The crystal structure is stabilized by inter-molecular N-H⋯N hydrogen bonds, linking the two independent mol-ecules into hydrogen-bonded dimers.

In the centrosymmetric title compound, [Ni(N(3))(2)(C(22)H(34)N(6))], the Ni(II) ion is coordinated by the four secondary N atoms of the macrocyclic ligand in a square-planar fashion with two N atoms of the azide ions in axial positions, resulting in a tetra-gonally distorted octa-hedron. An N-H⋯N hydrogen-bonding inter-action between the secondary amine N atom of the macrocycle and an adjacent...

We report the development of a method for direct Chan–Lam coupling arylboronic acid N -methyliminodiacetic esters (ArBMIDA). The process accommodates amine and alcohol nucleophiles to deliver wide range C–N C–O cross-coupled products in 34–99% yield (34 examples). This serves expand scope organoboron component that can be used directly this oxidative reaction provides opportunities streamlining...

In the title pyrimidine derivative, C(4)H(4)ClN(3), the 2-chloro and 4-amino substituents almost lie in the mean plane of the pyrimidine ring, with deviations of 0.003 (1) Å for the Cl atom, and 0.020 (1) Å for the N atom. In the crystal, molecules are linked via pairs of N-H⋯N hydrogen bonds, forming inversion dimers. These dimers are further linked via N-H⋯N hydrogen bonds, forming an undulat...
