描述了2，5-二氢-1，4，5-噻二氮杂卓S-氧化物的可切换的环收缩挤出反应，其允许在热条件下方便地获得哒嗪或在刘易斯酸介导的条件下方便地获得吡唑。
Switchable ring-contractive extrusion reactions of 2,5-dihydro-1,4,5-thiadiazepineS-oxides are described, which allow expedient access to pyridazines under thermal conditions or pyrazoles under Lewis acid-mediated conditions.
