nucleophilic substitution in mixed phosphonium-iodonium ylides was investigated. The iodonium group is replaced by such S-containing nucleophiles as the thiocyanate anion or thiourea, as well as by halide ions. The structure of the reaction product with the thiocyanate ion was established by X-ray diffraction. A one-pot process involving the nucleophilic substitution and the Wittig reaction was developed
研究了混合鏻-碘鎓叶立德中的亲核取代。碘鎓基团被诸如硫氰酸根阴离子或硫脲之类的含硫亲核试剂以及卤离子取代。通过 X 射线衍射确定了与硫氰酸根离子反应产物的结构。开发了涉及亲核取代和 Wittig 反应的一锅法。
