butyraldehyde (IV) affords an opportunity to observe the reactions of two such radicals. The syntheses of I11 (bp 71-72”(13 mm), n Z 5~ 1.4210) and IV (bp 66-67”(10 mm), lit. 70-72'(12 mm9), n Z 5~ 1.4183) were achieved by acetylation of the corresponding unsaturated alcohols followed by the reductive ozonolysis of the esters. The structures and purity
