Dichlorocarbene, generated from ethyl trichloroacetate and sodium ethoxide, reacts with 2,3-dimethyl-5,6-dihydro-1,4-oxathiin to give 7,7-dichloro-1,6-dimethyl-2-oxa-5-thiabicyclo[4,1,0]heptane, and with 2,3-dimethyl-5,6-dihydro-1,4-dithiin to give 6-chloro-2,3-dihydro-7-methyl 5-methylene-5(H)-1,4-dithiepin. Both products were oxidised to the corresponding sulfone.
由三氯乙酸乙酯和乙醇钠生成的二氯卡宾与2,3-二甲基-5,6-二氢-1,4-氧杂ath啶反应生成7,7-二氯-1,6-二甲基-2-氧杂-5-噻吩二环[4,1,0]庚烷,并与2,3-二甲基-5,6-二氢-1,4-二硫辛形成6-氯-2,3-二氢-7-甲基5-亚甲基-5(H)-1,4-二硫平。两种产物均被氧化成相应的砜。
