摘　　要：以RuC l2(PPh3)3为原料,EtOH/KOH组合试剂为氢供体,通过升温方式控制,方便地合成了产率为91.9%的RuHC l(PPh3)3,其结构用NMR、MS、IR、IE和ICP得到了表征;通过IR,NMR分析研究表明,反应经过了[Ru]-OEt中间体过程.用RuHC l(PPh3)3作为催化剂,无溶剂条件下可以有效地催化1-十八烯的双键异构化,在180℃时,催化剂与1-十八烯的摩尔比为1∶200,反应时间为24 h时,1-十八烯的转化率为94.6%.The reduction of RuCl2 （PPh3 ）3 with EtOH/KOH conveniently resulted in RuHCl（ PPh3 ）3 of up to 90% yield, which was characterized with NMR, MS, IR, IE and ICP, and it discovered that the synthetic process involved [ Ru]-OEt intermediate according to IR and NMR; 1-octodecene isomerization was effectively catalyzed by RuHCI（ PPh3 ） 3 with solvent-free, the conversion of 1-octodeeene reached 94.6% in the conditions of the temperature - 180℃, the reaction time -24 hour and the molar ratio of catalyst to 1-octodecene - 1： 200.
