Under a nitrogen atmosphere, 0.2 g PdCl₂, 1.12 g Ph₂PCH₂CH₂PPh₂, and 12 ml dimethyl sulfoxide were mixed and heated to 140 °C to form a homogeneous solution, which was initially light red. The oil bath was removed, and the mixture was stirred vigorously for 30 min. Then, 0.3 ml (0.226 g) of hydrazine hydrate was slowly added dropwise. The reaction proceeded vigorously, and nitrogen gas was produced, turning the solution dark brown. The solution was cooled in a water bath, and brown crystals precipitated at approximately 125 °C. After slowly cooling to room temperature, the crystals were centrifuged, washed twice with 5 ml ethanol and twice with 5 ml diethyl ether, and dried under vacuum to obtain orange crystals, with a yield of approximately 78.2%. |
