摘要

Abstract The reactions of sterically crowded cycloalkanethiones of type 2 with CHCl 3/NaOH under phase-transfer catalysis (PTC) with benzyl (triethyl) ammonium chloride (TEBA) as catalyst afforded the correspondinggem.-dichlorothiiranes' of type 3 in good yields (cf. Scheme 2 and Table). The desulfurization, which, in some cases, occurred spontaneously, led to (dichloromethylidene) cycloalkanes of type 4. Similar results were obtained using ...
