2-[2-(5-Bromothiophen-2-yl)-4,5-diphenyl-1H-imidazol-1-yl]-3-phenylpropan-1-ol
In the title compound, C28H23BrN2OS, the dihedral angles formed by the imidazole ring with the 5-bromo-thio-phenyl and phenyl rings are 76.90 (8), 34.02 (10) and 80.93 (11)°, respectively. The chiral centre maintains the S configuration of the l-phenyl-alaninol starting material. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds, forming chains running parallel to the a-axis direction.
متن کاملPd-catalyzed 5-endo-trig-type cyclization of β,γ-unsaturated carbonyl compounds: an efficient ring closing reaction to give γ-butenolides and 3-pyrrolin-2-ones.
The 5-endo-trig-type cyclization has been performed using a Pd-bis(isoxazoline) catalyst. The present cyclization of β,γ-unsaturated carbonyl compounds gave γ-butenolides and 3-pyrrolin-2-ones in good to excellent yields.

In the title compound, C(19)H(17)ClNO(3)P, the P atom exhibits a distorted tetra-hedral configuration. In the crystal, pairs of inter-molecular N-H⋯O(P) hydrogen bonds form centrosymmetric dimers.
متن کاملDichloridobis(2-chlorobenzyl-κC)[5,6-diphenyl-3-(2-pyridyl)-1,2,4-triazine-κ2 N 2,N 3]tin(IV)
The asymmetric unit of the crystal structure of the title compound, [Sn(C(7)H(6)Cl)(2)Cl(2)(C(20)H(14)N(4))], contains two independent mol-ecules. Each Sn(IV) atom is chelated by the bipyridine-like N-heterocycle and exists in a distorted trans-C(2)SnCl(2)N(2) octa-hedral coordination environment. One chloro-benzyl substituent is disordered in each mol-ecule in 0.5:0.5 and 0.778 (2):0.222 (2) r...
متن کامل2-(2-Chlorophenyl)-3-methyl-5,6-diphenyl-2,3-dihydropyrazine
In the title mol-ecule, C(23)H(19)ClN(2), the heterocyclic ring adopts a screw-boat conformation, with all substituents equatorial. The benzene ring at position 2 makes dihedral angles of 77.88 (12) and 76.31 (12)° with the phenyl rings at positions 5 and 6, respectively. The dihedral angle between the phenyl rings at positions 5 and 6 is 70.05 (10)°. The Cl atom is disordered over two position...
