Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: (S)-Propane-1,2-diamine dihydrochloride, is researched, Molecular C3H12Cl2N2, CAS is 19777-66-3, about Cold Crystallization of Chiral Schiff-Base Nickel(II) Complex Having Alkyl Chains and a Characteristic Methyl Group.Related Products of 19777-66-3.
Mols. exhibiting cold crystallization, an exothermic phenomenon in heating following supercooling, can be used as a heat storing material. However, examples in nonpolymers are still few. A chiral Schiff-base nickel(II) complex, which had a characteristic Me group and long alkyl chains, exhibited complicated thermal behavior including cold crystallization The Me group was a steric barrier to dimerization and mol. stacking, leading to the supercooled state. The thermal behavior of enantiomer was different from that of racemate.
In some applications, this compound(19777-66-3)Related Products of 19777-66-3 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
