Introduction

Dimethyldioxirane (DMD), a nonmetal organic oxidant, has the ability to transfer an oxygen atom to a wide range of substrates and functionalities, including C=C and C-H bonds in hydrocarbons as well as atoms containing lone pairs such as sulfide, [1] primary and secondary amines. [2] This nonmetal electrophilic oxygen transfer agent is the reagent of choice for most epoxidation reactions (better than MCPBA) due to its substrate-induced selectivity, specificity, and reactivity under mild conditions (at 0-25 °C and neutral pH). It reacts rapidly and in high yield, is easy to handle and applicable to acid- or base-sensitive substrates, and it can be used to synthesize hydrolytically labile oxyfunctionalized products. [3-4]

DMD-mediated halogenations, [5a] hydroxylations, [5b] and oxidations are widely used in the chemistry of flavonoids, low-molecular-weight natural compounds and in expanding the organoborane chemistry. [6a] [b] It also acts as a G-specific chemical sequencing agent and is a new source of singlet oxygen generation. [7a,b]
