Electric Literature of 4254-15-3, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 4254-15-3, (S)-Propane-1,2-diol, introducing its new discovery.
Regioselective Cyclodehydration of Chiral Diols with Diethoxytriphenylphosphorane, Triphenylphosphine-Tetrachloromethane-Potassium Carbonate, and Triphenylphosphine-Diethyl Azodicarboxylate Reagents. A Comparative Study
The regioselectivity of cyclodehydration of chiral diols has been examined with the reagents diethoxytriphenylphosphorane, triphenylphosphine-tetrachloromethane-potassium carbonate, and triphenylphosphine-diethyl azodicarboxylate. (S)-(+)-Propane-1,2-diol and (R)-(-)-pentane-1,4-diol afford 80-87percent retention of stereochemistry at the chiral carbon in the ether while (S)-(+)-phenylethane-1,2-diol affords essentially racemic styrene oxide with all three reagents.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 4254-15-3. In my other articles, you can also check out more blogs about 4254-15-3
