Abstract

In the preceding paper3 evidence was presented to show that the formation of 2, 4, 6- triphenylpyrylium salts from acetophenone does not proceed by ejection of a methyl group iron an intermediate pyran as had been suggested previously. Although such elimination of a hydrocarbon fragment does not occur in this particular instance] the possibility that, under favorable conditions, elimination of a methyl group from an oxygen heterocycle may occur ...
