3-tetrachloroalkanes were selectively reduced by silicon hydrides to give chloroform, 1,1-dichloroethane, and 1,1,3-trichloroalkanes, respectively, in high yields in the presence of catalytic amounts of phosphine complexes of ruthenium(II) such as RuCl2(PPh3)3, RuHCl(PPh3)3, RuH2(PPH3)4, and RuH(SiMe2Cl)(PPh3)3. Reactivities of a wide variety of silicon hydrides towards the dechlorination also were estimated
用氢化硅选择性还原四氯化碳,1,1,1-三氯乙烷和1,1,1,3-四氯烷烃,分别在高温下生成氯仿,1,1-二氯乙烷和1,1,3-三氯烷烃。在催化量的钌(II)膦络合物如RuCl 2(PPh 3)3,RuHCl(PPh 3)3,RuH 2(PPH 3)4和RuH(SiMe 2 Cl)(PPh 3)3。还估计了各种氢化硅对脱氯的反应性。可以通过连续的氧化加成,还原性消除和钌-膦配合物上的氢-卤素交换来解释催化循环。
