Steps:

2.2 Standard Procedure fortheHydrogenationofSubstrates
General procedure: Hydrogenation reactions were carried out in a stainless steelautoclave Parr reactor equipped with an internal cooling system,a temperature control unit and a sampling valve. In atypical experiment, the reactor was pre-heated, evacuatedand flushed with nitrogen and cooled to room temperature.A solution of styrene (0.25ml, 2.10mmol) and complexPd3 (0.0014g, 0.0027mmol) in toluene (20ml) was thenintroduced using a cannula. The reactor was then purgedwith hydrogen gas several times, and then the desired pressureand reaction temperature set and stirred for the specifiedtime. At the end of the reaction period, the reactor wasthen cooled, the gas supply closed and excess hydrogen gasvented off. The samples were then collected for GC analysesusing a syringe equipped with 0.45μm micro filtersand analysed by a Varian CP-3800 GC (ZB-5HT Column30m × 0.25mm × 0.1μm) to establish percentage conversions.The percentage conversions were calculated by comparisonof the substrate peak areas to those of the products,assuming 100% mass balance. The kinetics reactionswere done through monitoring the change in substrate consumptionover time at regular intervals. The rate constantswere then derived from graphical plots of ln[substrate]0/[substrate]t versus time. The catalysis products were identi
