抱歉,各位!我把分子式写错了。应该是:PdCl2(PPh3)2,汉语名称是:双(三苯基磷)二氯化钯。

3.54gPdCl2+4g anhydrous LiCl in 150ml of methanol was heated at 60C until the red-brown solid had dissolved (15min).A solution of 13.1g of triphinylphosphine in 25ml of warm (50C)THF was added in one portion. the mixture was stirred at about 50C until the brown colour had disappeared completely(about 1 to 2 hour).the yellow suspension was cooled to room temperature and then filtered on sintered glass . the solid was washed twice with 30ml potions of methanol and once with dry ether. after drying in vacuo,the product was obtained in 90-95% yield.英文是一个一个敲的,照者原文,希望能给你帮助!
