Phenylselenenyl chloride addition to the 3-exomethylene-1-cepham gave mainly the seleno derivative at room temperature while the dichloro derivative was obtained in refluxing 1,2-dichloroethane. Compounds and transformed into the Δ2 and Δ3 chloromethyl isomer respectively.
在室温下,将苯硒烯基氯加到3-外亚甲基-1-cepham中,主要得到硒代衍生物,而在回流的1,2-二氯乙烷中得到二氯衍生物。化合物和转化为Δ 2和Δ 3分别氯甲基异构体。
