Dioxiranes. 20. Preparation and properties of some new dioxiranes
Murray, Robert W.,Singh, Megh,Jeyaraman, Ramasubbu
, p. 1346 - 1351 (2007/10/02)
The in situ method for producing dioxiranes has been modified to permit the isolation in ketone solution of some nonvolatile dioxiranes. The dioxiranes have been characterized spectroscopically and, in some cases, by chemical reactions.
