A further example for the ad -el mechanism is the reaction of OH with the strong reductant ascorbic acid. This reaction, which leads to the oxidation of ascorbic acid to yield the ascorbate radical, proceeds by addtion to the olefinic bond of the reductone function followed by elimination of OH Abe, A.

The first reports of the formation of olefins from MeOH date back to 1880 [21], In 1914, Semagiotto [30] reported the decomposition of methanol by PjO,. The reaction products were propylene, butene, hexene, and hexane. Adkins and Perkins [31] studied the reaction... 

The aldol, Perkin, and Knoevenagel condensations of active methylene compounds with aldehydes give olefins which are probably derived from the intermediate alcohols, as is true in the aldol condensation shown above. The Perkin, Knoevenagel, and Claisen reactions are described in further detail in Chapter 9, Carboxylic Acids.
