摘要：
Dimethyldioxirane was found to oxidize electron-rich thiophene derivatives, including sterically hindered thiophenophanes, to the corresponding thiophene 1,1-dioxides in excellent yields. Electronwithdrawing groups on a thiophene ring substantially retarded the oxidation, but dimethyldioxitane remained superior to other reagents. © 1990.
