Hydrogen bonds concept

When a major portion of Guncotton was dispersed with acetone-alcohol and the residual portion with one of the above compds, equal weights of the compds were superior to dibutyl phthalate and to triacetin first, with respect to time reqd for complete dispersion and secondly, in producing solns of low viscosity Ref A.J.

Extensive molecular dynamic simulations of proline-catalysed asymmetric aldol condensation of propionaldehyde in water have revealed that the stereoselectivity can be attributed to differences in transition-state solvation pattems. " The hydrogen bond concept has been applied to design new proline-based organocatalysts. " 4-Hydroxyproline derivatives bearing hydrophobic groups in well-defined orientations have been explored as catalysts in water an advantage of aromatic substituents syn to the carboxylic acid moiety has been attributed to a stabilizing transition-state hydrophobic interaction and this is supported by quantum mechanics (QM) calculations. " Catalysts and solvents were screened for reaction between cyclohexanone andp-nitrobenzaldehyde.
