18–20 at 650 °C (10−2–10−3 Torr) gave products derived from the corresponding iminyl and thiophenoxylradicals. In all cases, benz[d]isothiazoles (e.g., 26) are formed as major products viaSHi mechanisms though the yields are greatest with the iminyl precursors. Alternative pathways observed from the thiophenoxyls in specific cases include the formation of the anilinobenzothiophene 36 and of dibenzothiophene
