trans-p-Cyanostyryl(pyridine) cobaloximes (I and II) and cis and trans-p-methoxystyryl(pyridine)cobaloximes (V and VI) were prepared by the reaction of the reduced form of cobaloxime, bis(dimethylglyoximato)(pyridine) cobalt(I), with cis and trans-p-cyanostyryl bromides and with cis and trans-p-methoxystyryl bromides, respectively. The styryl-type cobaloximes thus obtained retained the stereochemistry, cis or
顺式和反式-对氰基苯乙烯基(吡啶)钴肟(I和II)和顺式和反式-对甲氧基苯乙烯基(吡啶)钴肟(V和VI)是通过还原形式的钴肟,双(二甲基乙醛肟)(吡啶)钴(I),分别具有顺式和反式-对-氰基苯乙烯基溴化物以及顺式和反式-对甲氧基苯乙烯基溴化物。如此获得的苯乙烯基型钴肟保留了起始溴化物的立体化学,顺式或反式。这些苯乙烯基型钴肟(I、II、V 和 VI)以及顺式和反式苯乙烯基(吡啶)钴肟(III 和 IV)在极性或非极性溶剂中的溴化得到苯乙烯基型溴化物,其保留的配置。这些钴肟与 DMF 中的醋酸汞 (II) 的汞化产生苯乙烯基型汞,再次保留原始构型。
