Anisotropy shift and Raman bandwidth studies in carbonyl containing molecule o-chlorobenzaldehyde: Role of repulsive forces

The analysis of Raman anisotropy shift as a function of solvent concentration shows the weakening of pair interaction of the molecules due to the influence of solvent-induced perturbations. The present study deals with the effect of dielectric constant of the medium on the non-coincidence effect (anisotropy shift) and the role of van der Waals’ volume on the anisotropic Raman bandwidth. The C O stretching vibration of o-chlorobenzaldehyde (OCBD) molecule was studied in various polar and non-polar solvents namely CCl 4, CH 3CN, C 6H 5Cl and CH 3C 6H 5. The data on anisotropic bandwidth are interpreted using the van der Waals’ volume within the framework of lineshape theory of Bratos and Tarjus, while the Onsager–Fröhlich model on non-coincidence effect has been tested. Our study shows that the repulsive potential of the type e −αR is playing an important role in the OCBD–solvent interactions. The vanishing of anisotropy shift (non-coincidence effect) on dilution may be explained on the basis of repulsive forces playing a significant role in solute–solvent interactions.

Synthesis of 2-amino-2-deoxo-5-deazaflavins and related compounds

10-Alkyl-2-amino-2-deoxo-5-deazaflavins were prepared by the condensation of 2-amino-6-chloro-5-formylpyrimidin-4(3H)-one with the corresponding N-alkylanilines. 2-Amino-10-p-tolyl-2-deoxo-5-deazaflavin was prepared by the condensation of 2-amino-6-p-toluidinopyrimidin-4(3H)-one with o-chlorobenzaldehyde. Some reactivities of 2-aminopyrimidin-4(3H)-ones are described.

Asymmetric Darzens condensation on chiral η 6Cr(CO) 3 complexed benzaldehydes

Enantioselective Darzens condensation has been achieved from optically active ortho substituted benzaldehyde(tricarbonyl)chromium complexes. The enantiomeric excesses were very high with 2-methoxy and 2-chloro benzaldehyde(tricarbonyl)chromium and the corresponding epoxides obtained were nearly optically pure.
