Abstract

We have recently postulated the existence of allene oxide la and spiro dioxide 2a as unisolated reactive intermediates in the peracid oxidation of tetramethylallene.'These species were invoked to provide a rational basis for the array of products (3a-6a) which was obtained from this reaction. Substantial supporting evidence for this proposal is herein presented by virtue of the isolation and characterization of 5-t-butyl-2, 2-dimethyl-1, 4- ...
