the kinetics and mechanisms of nucleophilic substitution and elimination reactions of halo olefins1–3 so the aim of this work is to prepare compounds of the type C6H5CCI=CHSO2 and to study their behaviour towards elimination and substitution reactions. Earlier preparation of these sulfones by thermal or copper-catalyzed addition of aryl sulfonyl bromides and chlorides to phenylacetylene reported a mixture
摘要 由于我们的兴趣是研究卤代烯烃 1-3 的亲核取代和消除反应的动力学和机制,因此这项工作的目的是制备 C6H5CCI=CHSO2 类型的化合物并研究它们对消除和取代反应的行为。早期通过将芳基磺酰溴和氯化物热或铜催化加成到苯乙炔来制备这些砜,报道了 E- 和 Z- β-卤乙烯基砜或仅 E-异构体 4-7 的混合物。五氯化磷与苯甲酰基芳基砜的反应被研究作为制备β-氯乙烯基砜的可能途径。
