Safranine in its ground state in the pH range from 2.5 to 6.0 is largely present in its monoprotonated form. Laser excitation followed by intersystem crossing leads to the triplet state. In the triplet state, the favorable species is the diprotonated form in this pH range. The rate constants for pro
Sodium borohydride-rhodium chloride in hydroxylic solvent was proved to be very useful for the reduction of aromatic nuclei to the corresponding saturated cycles under mild conditions.
In hydroxylic solvents, N-1-adamantyl-N-p-tolylcarbamoyl chloride undergoes a facile rate-determing ionization with very little assistance from nucleophilic solvation (very low sensitivity to changes in solvent nucleophilicity). In the relatively nucleophilic aqueous ethanol or aqueous acetone, the
## Abstract The dynamics of the molecular rotation of 2(1__H__)‐pyridone and 1‐methyl‐2(1__H__)‐pyridone in toluene, carbon tetrachloride, methanol and water have been investigated at 305 K by ^13^C and ^2^H NMR. Both chemical shifts and relaxation times show that 2‐pyridonc forms stable hydrogen‐b
