The preparation of some novel four-carbon electrophiles and electrophile intermediates is described. Thus, the chlorobutenyl sulfone (5), the iodobutynyl sulfone (6) and the hitherto unreported chlorobutynyl sulfone (4) were prepared. The novel intermediates, containing a chelating imidazolyl functionality, the N- methylimidazolyl sulfides (13)-(15) were also prepared. However, they polmerized rapidly, thus preventing further synthetic manipulations. The preparation of the α-( trimethylsilyl ) butadienyl sulfones (17) and (18) is described and the mode of formation of the intermediate α- trimethylsilyl sulfides (21) and (22) from the trimethylsilylbutenyl sulfide (27) is discussed.
本文介绍了一些新型四碳亲电体和亲电体中间体的制备方法。因此,制备出了氯丁烯基砜(5)、碘丁炔基砜(6)和迄今未报道过的氯丁炔基砜(4)。此外,还制备出了含有咪唑螯合官能团的新型中间体 N-甲基咪唑砜 (13)-(15)。然而,它们很快就聚合了,因此无法进行进一步的合成操作。本文介绍了 α-(三甲基硅基)丁二烯基砜 (17) 和 (18) 的制备方法,并讨论了由三甲基硅基丁烯基硫醚 (27) 生成中间体 α-三甲基硅基硫化物 (21) 和 (22) 的模式。
