determined by single-crystal X-ray diffraction analysis. The ruthenium complexes were further evaluated as catalysts in the redox isomerization of allyl alcohols to carbonyl compounds. Complex [(η6-p-cymene)RuCl2(1-κP)] (5b) proved to be a particularly attractive catalyst, being both readily available and catalytically active. Substrates with unsubstituted double bonds were cleanly isomerized with
Ph2P-fc-CONHCH2CH2OH (1, fc = ferrocene-1,1'-diyl) 及其新合成的同系物 Ph2P-fc-CONHCH(CH2OH)2 (2) 和 Ph2P-fc-CONHC(CH2OH)3 (3) ),转化为一系列 (η6-

芳烃是苯、
对伞花烃和六
甲苯,L = 1–3。所有化合物均通过多核 NMR 和 IR 光谱、质谱和元素分析进行表征。通过单晶X射线衍射分析确定了2、3、3O(由3氧化产生的氧化膦)、5c·
CH2Cl2和6c·Et2O的分子结构。
钌配合物被进一步评估为
烯丙醇氧化还原异构化为羰基化合物的催化剂。复合物 [(η6-p-cymene)RuCl2(1-κP)] (5b) 被证明是一种特别有吸引力的催化剂,既容易获得又具有催化活性。具有未取代双键的底物在
