Abstract
Reaction of di-tert-butylacetylene (la) with ozone in<-40 OC aprotic solvents upon warming leads to pivalic anhydride, pivalil, and pivalic acid, with evolution of isobutane, isobutene, carbon dioxide, and carbon monoxide. Spectral and chemical evidence indicated the presence of at least two labile intermediateg in the reaction. Ozonolysis of the alkyne in the presence of compounds containing a hydroxyl function led to their pivaloyl derivatives with ...
