In the following reaction sequence
\[ \begin{array}{l} \mathrm{HNEt}_{2}+\mathrm{CS}_{2} \xrightarrow{\mathrm{KOH}} \mathrm{P} \xrightarrow{\text{aq. soln}} \mathrm{R} \\ \mathrm{I}_{2} \xrightarrow{[\mathrm{CpMo(CO)_3}]_2} \mathrm{S} \end{array} \]
Where dtc = dithiocarbamate and tds = thiuramdisulfide. Identify P, R and S. Cp$=\eta^{5}\text{-}\mathrm{C_5H_5}$
PRS
