New Advances in Chemical Research, May 2021. The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic and spectroscopic. An article , which mentions Recommanded Product: 19132-06-0, molecular formula is C4H10O2. The compound – (2S,3S)-Butane-2,3-diol played an important role in people’s production and life., Recommanded Product: 19132-06-0
The C2 amidine derivative (S,S)-1, as a twisted chiral dual acceptor for hydrogen bonding, was designed and synthesized. Enantioselective binding between (S,S)-1 and a series of diol enantiomers was investigated by NMR spectroscopy. High enantioselection above 1.0 kcal/mol was achieved in CDCl3. The association mode based on dual N···HO interactions was confirmed by intermolecular NOEs.
By the way, Recommanded Product: 19132-06-0, if you are interested in learning more fun chemistry with your kids, get your hands into one chemistry set now, and start enjoying the best part of chemistry: experiments about 19132-06-0
