The effect of leaving group on both thermal stability and reactivity towards nucleophilic substitution with acetate, N-butylimidazole, and sulfur was examined. The material containing the iodomethyl microstructure (r-IIIR) readily underwent nucleophilic substitution at low temperatures; however, it was ...

ORGANIC REACTIVITY, IONIC LIQUIDS, NUCLEOPHILIC SUBSTITUTION REACTIONSIonic liquids have been advanced as alternative solvents for organic reactions. In this paper, the principal findings of studies on nucleophilic substitutions in ionic liquids are reviewed. Thus our examination of halides (Cl-, Br- ...

The nucleophilic reactivity of oxo ligands in the groups M VI O 3 in the trigonal complexes [(Me 3 tacn)MO 3 ] (M = Mo ( 1 ), W ( 10 )) and [(Bu t 3 tach)MO 3 ] (M = Mo ( 5 ), W ( 14 )) has been investigated. Complexes 1 / 10 can be alkylated with MeOTf to...
Reactivity of hexachlorocyclotriphosphazene towards alkyl-lithium reagents 喜欢 0 阅读量: 27 作者:H Winter,JCVD Grampel 摘要: Reactions of (NPCl2)3 with LiMe or LiBut and an excess of propan-2-ol at –60 °C in tetrahydrofuran lead to complex reaction mixtures containing cyclic derivatives in ...
In this regard, the search for well-described multi-iron nitrido model complexes and investigations on controlling their reactivity towards ammonia formation have long been of great challenge and importance. Here we report a well-defined thiolate-bridged FeIVFeIVμ-nitrido complex featuring an ...
