Wilkinson's catalyst is the common name for chlorotris(triphenylphosphine)rhodium(I), a coordination compound with the formula RhCl(PPh3)3 (Ph = phenyl). It is named after the chemist and Nobel Laureate, Sir Geoffrey Wilkinson who popularized its use. Wilkinson’s catalyst is a homogeneous organometallic catalyst, RhCl(PPh3)3, which catalyzes the hydrogenation of olefins. Catalytic processes can be categorized into two groups: 1) homogeneous catalysis which is a process where the catalysts and reactants remain in the same phase; and 2) heterogeneous catalysis which defines as where the reactants and catalysts are in different phases. The catalytic discovery was made independently by Wilkinson and Coffey in 1964. Wilkinson completely explored the scope, selectivity, and mechanism of the complex which catalyzes the hydrogenation of olefins. This compound is now commonly referred to as “Wilkinson’s catalyst\".

生产方法
在500ml圆底烧瓶中,将2g三水合氯化铑(III)溶解在70ml乙醇中,在这只烧瓶上安装进气管、回流冷凝器、气体导了管和鼓泡器。加入12g三苯膦(从乙醇中新结晶以除去三苯膦氧化物)在350ml热乙醇中的溶液,并用N2吹洗烧瓶。回流约2h。将生成的晶状产物从热溶液中收集在布氏漏斗或玻璃砂芯漏斗上。用小份的无水乙醚共50ml洗涤,得深红色产物6.25g. 如果使用乙醇的总量为200ml或更少些,并将溶液回流约5min,则得到一种橙色的同分异构体。这人物质中往往含有少量的红色产物,并且在继续回流时,橙色晶体就缓慢地转变成红色变体。 在制备过程中使用的过量三苯膦可以如下回收:向乙醇滤液中加水直到开始产生沉淀,在一只塞闭的烧瓶中将溶液放置2～3天后,三苯膦就结晶出来了,从乙醇到乙醇-苯(1 1. 石蜡加氢催化剂;
