The electrophylic COOH group is regarded as responsible for the deviations. The spectra are highly specific and make possible a ready characterization of any acid. This should prove useful in any analytical work involving these acids, particularly the higher members....
Ab initio calculations have been carried out on a group of substituted monosilabenzenes. Twelve different substituents are considered (Cl, F, SH, OH, PH2, NH2, CH3, SiH3, N02, CN, OCH3, COOH), each placed in the four unique positions on the ring. The relative energies and stabilities...
Inclusion of the benzene group in the ligand permitted use of a simple spectrophotometric method for the measurement of equilibrium concentrations. It was shown that equilibrium could be attained rapidly, in under 2 days, if the detergent was initially mixed with the protein and allowed to ...
can also be F, Cl or Br, with the proviso that Q and R1 must not simultaneously be radicals selected from the group consisting of F, Cl, Br, CF3 and -OH, where, in compounds in which all radicals A1 are selected from the group consisting of 1,4-phenylene which is unsubstituted or...

The Bräse group also performed the reaction at room temperature within 5d, using 1,4-dioxane as a solvent. This combination had given the best results in the case of hydratropaldehyde with 87% conversion and 67% ee. In this case, an increased yield of 72% was observed, but the ...
The invention comprises 2,4,6 - triiodo - 3 - hydroxy-benzene derivatives of the general formulawherein R is hydrogen or a -CH(R3)-(CH2)n-COOH group, R3 being hydrogen, an alkyl group containing 1-6 carbon atoms or a substituted or unsubstituted phenyl group and n is 0, 1, 2, ...
