Reactions of Sallyl systems (allyl sulphides of RSallyl type, where R=Et, allyl, Ph, Me3C, Ph3C, as well as of allyl phenyl sulphoxide, allyl phenyl sulphone, 2,5-dihydro-1,1-dioxothiophene) with [RuClH(CO)(PPh3)3] and other ruthenium compounds have been investigated. Double-bond migration was observed in the case of allyl trityl sulphide, allyl t-butyl sulphide and both sulphones, that is, where
的反应小号allyl系统(RSallyl类型的烯丙基硫化物,其中R =的Et,烯丙基中,Ph中,Me 3 C,博士3 C,以及烯丙基苯基砜,烯丙基苯基砜,2,5-研究了带有[RuClH(CO)(PPh 3)3 ]的二氢-1,1-二氧代噻吩)和其他钌化合物。在烯丙基三苯甲基硫醚,烯丙基叔丁基硫醚和两种砜中都观察到双键迁移,也就是说,硫的配位性能不太强。高,得到(合成的ë) -和(Ž)-RSCHCHCH 3(R =我3 C,ž:È= 96:4且Ph 3 C,ž:È = 92:8),(ê)PhS(O 2)CHCHCH 3和从各自的烯丙基系统2,3-二氢-1,1- dioxothiophene被描述。分离了烯丙基苯硫醚与[RuClH(CO)(PPh 3)3 ]的模型反应中形成的双核Ru配合物,并已解析其结构。之间的反应的机理小号allyl系统和[RuClH(CO(PPH 3)3,提出]。
