Tandem 1,5-hydrogen transfer and decarbonylation in the flash vacuum pyrolysis of 5-vinyl-3-methyl-1,2-dioxane
Abstract
Intramolecular 1,5-transfer of a primary hydrogen atom is the dominant behaviour in dioxyl diradicals formed by flash vacuum pyrolysis of 5-substituted 3-methyl-1,2-dioxanes and is followed by decarbonylation when the substituent is the vinyl group.
