Route of Synthesis (ROS)
| Conditions | Yield |
| With hydrazine hydrate In methanol cellulose (5 g) added to soln. of PdCl2 (0.443 g) in MeOH; stirred (15 min); 80% hydrazine hydrate added dropwise (15 min); stirred (12 h, room temp.); solid filtered; washed with methanol and acetone; dried (vac.); | 99% |
| With hydrogenchloride; hydrazine In water | 98% |
| With formic acid In not given refluxing a soln. of PdCl2 and HCOOH for 30 min; decantation, washing with water, drying for 2 h at 120°C; | 96% |
| With perchloric acid; 2,4-dichlorophenol; phosphododecatungstate In water Kinetics; Irradiation (UV/VIS); irradiated (>320 nm) at pH 1 (HClO4) at 18.3°C for 150 min; ppt. collected, dried, elem. anal.; | 83% |
| With 2,3,5,6-tetramethyl-1,4-bis(trimethylsilyl)-1,4-diaza-2,5-cyclo-hexadiene In tetrahydrofuran at 20℃; for 12h; Inert atmosphere; Toa THFsuspension (5.0 mL) of 89 mg (0.50 mmol) of brownpalladium (II) chloride prepared in a Schlenk tube under an argonatmosphere was added 141mg (0.50 mmol) of Me4BTDP in THF The solution (5.0 mL) was added dropwise at room temperature.It quickly became a black suspension.After 12 hours, stirring was stopped and the mixture was allowed to stand to precipitate a black solid.The brown supernatant was filtered off and the resulting precipitate was washed three times with 5.0 mL of THF.The solid after washing was dried to obtain 27 mg of black palladium powder (0.25 mmol, yield 50%). | 50% |
