Question

(QUESTION 2 continued) (ii) The active form of the catalyst used for the catalytic enantiospecific hydrogenation of \( \alpha \)-acetamido cinnamic esters (see below for formula of ester) is given below which has two solvent molecules on the metal centre. (a) Show how the active catalyst is prepared, (b) State what solvent is used in the catalytic cycle, (c) Sketch how the catalyst coordinates to following the \( \alpha \)-acetamido cinnamic ester. \( \mathrm{CH}_{3} \mathrm{C}(\mathrm{O}) \mathrm{NHCH}\left(\mathrm{COOCH}_{3}\right) \mathrm{CHPh} \)
