4,4′-(Butane-1,4-diyl)bis(4-methyl-1,2-dioxolane-3,5-dione)

Abstract

Over the past decades, studies of cyclic diacyl peroxides have shown superior or even fundamentally new reactivity compared to their acyclic counterparts in various reactions. Previously, the scope of cyclic diacyl peroxides was limited to the mono peroxy compounds. The first doubled cyclic diacyl peroxide is presented herein. The diperoxide was characterized by NMR spectroscopy, mass spectrometry, and IR spectroscopy. The structure of 4,4′-(butane-1,4-diyl)bis(4-methyl-1,2-dioxolane-3,5-dione) was confirmed by X-ray diffraction analysis. The novel diperoxide was prepared in a 55% overall yield in three steps from dibromobutane and diethyl methylmalonate.

“…Cyclic diacyl peroxides were first synthesized in the 1950s [12,13], and their chemical properties are still being intensively studied [14,15]. A search for new interesting structures based on cyclic diacyl peroxides continues as well, and recently a doubled cyclic diacyl peroxide has been reported that may be useful for polymer chemistry [16]. Cyclic diacyl peroxides are utilized in dihydroxylation, dioxygenation [17][18][19][20][21][22][23], and oxyamination [24] of alkenes.…”
