Synthesis and Characterization of 2-(α-p -Substituted phenyl-α-benzimidazolo) methyl benzoxazole

2-p-substituted phenyl-2-benzimidazolo acetonitriles (1a-5a) were prepared by the reaction of benzimidazole , p-substituted benzaldehydes and Sodium cyanide. A series of 2-(α-p -Substituted phenyl-αbenzimidazolo) methyl benzoxazoles (1b-5b) were synthesized by the reaction of 2-p-substituted phenyl-2benzimidazolo acetonitrile(1a-5a) and o-aminophenol in presence of Conc. HCl. These compounds we...

Reactivities of Substituted α-Phenyl-N-tert-butyl Nitrones

In this work, a series of α-phenyl-N-tert-butyl nitrones bearing one, two, or three substituents on the tert-butyl group was synthesized. Cyclic voltammetry (CV) was used to investigate their electrochemical properties and showed a more pronounced substituent effect for oxidation than for reduction. Rate constants of superoxide radical (O2(•-)) reactions with nitrones were determined using a UV...

Phenyl 2,3-O-isopropyl­idene-1-thio-α-d-rhamnopyran­oside

In the title compound, C(15)H(20)O(4)S, a dioxolane ring is fused to the pyran ring of the sugar which carries a thio-phenyl substituent on the anomeric C atom. The dioxolane ring adopts an envelope conformation and the pyran ring system a distorted (4)C(1) chair. The structure is stabilized by O-H⋯O hydrogen bonds, forming centrosymmetric dimers that generate an R(2) (2)(10) ring motif. Additi...

Vibrational, conformational and electronic structure investigations of α,α'-dibromo-o-xylene, α,α'-dibromo-m-xylene and α,α'-dibromo-p-xylene.

The Fourier transform infrared (FTIR) and FT-Raman spectra of α,α'-dibromo-o-xylene (DBOX), α,α'-dibromo-m-xylene (DBMX) and α,α'-dibromo-p-xylene (DBPX) of the configuration BrCH(2)C(6)H(4)CH(2)Br have been recorded in the range 4000-400 and 4000-100 cm(-1), respectively. The conformational analysis of these compounds was performed. The complete vibrational assignment and analysis of the funda...
