在25℃和无氧条件下,以KBH_4为还原剂,测定了七种Mo-Fe-S簇合物(Ⅰ.(Et_4N)_4 [Mo_2Fe_2S_(10)]·2CH_3OH,Ⅱ.Mo_2Fe_2S_4(S_2CNEt(?))_5·CH_3CN,Ⅲ.(Bu_4N)_3[Mo_2FeS_3O],Ⅳ.(Et_4N)_3[Mo_2FeS_3O_2],Ⅴ.(Et_4N)_2[MoFeS_4(SCN)_2(OCH_3)_2]·3CH_3OH,Ⅵ.(Et_4N)_3 [Mo_2FeS_3O(OCH_3＇2],Ⅶ.(Et_4N)_4[Mo_2Fe_7S_(12)(SPh)_6]·6CH_3OH),三种Fe-S簇合物(Ⅷ.(Et_4N)_4[Fe_4S_4(S_2CNEt_2＇4],Ⅸ.(Bu_4N)_2[Fe_4S_4(SC(CH_3) 3)4],Ⅹ.(Bu_4N)[Fe_2S_3(SCH_2Ph)_2])和相关化合物的组合体系的催化乙炔还原活性.还在15℃和其它条件不变的情况下,测定了九种(?)由(NH_4)_2MoS_4和FeCl_3组成的不同组分的组合体系的催化乙炔还原活性.对上述实验结果进行了讨论.
Seven kinds of Mo-Fe-S cluster complexes (Ⅰ. (Et_4N) _4 [Mo_2Fe_2S_ (10)] · 2CH_3OH and Ⅱ.Mo_2Fe_2S_4 (S_2CNEt) were measured at 25 ℃ under anaerobic conditions with KBH_4 as reducing agent. (Et_4N) _3 [Mo_2FeS_3O_2], Ⅴ. (Et_4N) _2 [MoFeS_4 (SCN) _2 (OCH_3) _2] · 3CH_3OH, Ⅵ. (Et_4N) _3 [Mo_2FeS_3O] ) _3 [Mo_2FeS_3O (OCH_3’2], Ⅶ. (Et_4N) _4 [Mo_2Fe_7S_ (12) (SPh) _6] · 6CH_3OH), three kinds of Fe- The catalytic activity of acetylene for the combined system of [Bu4N4], [IX] (Bu4N) [Fe2S3 (SCH2Ph) 2] And other conditions were not changed, the catalytic reduction of acetylene of nine different combinations of (NH_4) _2MoS_4 and FeCl_3 were measured.The results of the above experiment were discussed.
