In a glove box, [RuCl2(PPh3)3] (0.25 mmol) was added to a schlenk flask equipped with a magnetic stir bar. The flask was then attached to a schlenk line and 3.4 mL of freshly distilled toluene added. The mixture was then rapidly stirred. A 1.7 mL toluene solution of Ph2PCH2CH2NH2, (0.50 mmol) in an NMR tube was then added via a cannula. Any residue in the NMR tube and cannula was washed into the flask with 1.7 mL of toluene. The light yellow mixture was then heated at 100 C. for 6 h. The yellow suspension that resulted was allowed to cool to RT before collecting the precipitate by filtration under Argon. The precipitate was then washed with 10.0 mL portions of toluene, three times (until colorless). The yellow solid was then dried in vacuo. Yield: 90%. Note: Excessive scraping of the product should be minimised to prevent the build-up of static electricity
