OPTICALLY ACTIVE QUATERNARY AMMONIUM SALTS BASED ON 8 <i>S,</i>9 <i>R </i>-(-)-CINCHONIDINE AND 4 <i>S,</i>5 <i>S</i>–(+)- <i> N <sup>4</sup></i>, <i>N <sup>4</sup></i>, <i>N <sup>5</sup></i>, <i>N <sup>5</sup></i>,2,2-HEXAMETHYL-1,3-DIOXOLANE-4,5-DIMETHANEAMINE (DIODMA)
Ionic type stabilizers for transition metal nanoparticles have been synthesized on the basis of natural alkaloid 8 S, 9 R -(-)-cinchonidine and optically active diamine 4 S,5 S –(+)- N 4, N 4, N 5, N 5,2,2-hexamethyl-1,3-dioxolane-4,5-dimethaneamine (DIODMA). The protonation sequence of nitrogen atoms in an alkaloid molecule has been determined on the basis of the analysis of 1Н NMR spectra of the obtained compounds. The scheme of reaction behavior is proposed. Some physical and chemical constants have been received for the synthesized compounds.
