从芳基二茂铁的汞化产物中首次分离出四种异环二取代产物 1-氯汞基-1'-芳基二茂铁。1-氯汞基-1'-芳基二茂铁与碘作用得到四种相应的碘代产物。氯汞基二茂铁及1-氯汞基-1'-芳基二茂铁经[ClRh(CO)~2]~2 催化偶联反应制得联二茂铁和三种1'、1'''-二芳基联二茂铁。以上化合物的组成与结构经元素分析、IR 和^1H NMR确证, 其中10种为新化合物。

Four 1-chloromercurio-1'-arylferrocenes were first isolated by chromatographic separation from the reaction mixture produced by the mercuration of arylferrocenes with mercuric acetate in dichloromethane-methanol, followed by the addition of lithium chloride, and were readily converted into four corresponding 1-iodo-1'-arylferrocenes by treatment with iodine in dichloromethane. Biferrocene and three 1',1'''-diarylbiferrocenes were synthesized by [ClRh(CO)~2]~2 catalyzed coupling reaction of the corresponding mercurials.

Key words: IODINATION REACTION, CATALYTIC REACTION, COUPLING REACTION
