Abstract

Abstract Treatment of various electron??deficient alkenes in DMSO with stable, dry, equimolar mixtures of either Me3S (O) I/KO t??Bu or Me3S (O) I/NaH cleanly afforded the corresponding substituted cyclopropanes in good yields and short reaction times (< 20 min for reactions at 50–60° C using 0.4–4.0 mmol alkene).
