place a flask in an ice/salt cold bath (ice and salt in the ratio 3:1) pour the solutions a) 3.08g Et2NH in 10 ml H2O and b) 2.0 g NaOH in 10 ml H2O into the flask and cool to approx. 2 C with stirring and continued cooling, 3.0 mL CS2 is added dropwise to the reaction mixture. this must be done so slowly that the temperature of the reaction mixture does not exceed 0 C. after the addition has finished, the stirring is continued for 10 min. mixture 16.4 g K3Fe(CN)6 in 50 ml H2O. is added dropwise to the reaction mixture at such a rate that the temperature does not exceed 5 C. the precipitate is isolated by suction filtration and washed with approx. 50 mL ice-cooled H2O until the yellowish color is gone. dissolve the washed precipitate in 50 mL 96% EtOH at approx. 50 C and cool for a few minutes. pour the solution in approx. 50 mL of ice-cooled H2O and isolate the precipitated crystals.

1) what the 13C NMR spectrum is expected to look like

2) give a suggestion for reaction mechanism
