Evidence is presented that the conversion of olefins of the type RCHC(CH3)2 to acetylenes of structure RCCCH3 by the action of sodium nitrite in aqueous acetic acid proceeds by a sequence involving two nitrations, Nef conversion of one nitro group to carbonyl, ring closure to an isoxazolone N-oxide and fragmentation to carbon dioxide, NO and the acetylene.
