摘要：
Alkoxides of magnesium, zinc, and aluminum thermally decompose at 195-340 °C to give a hydrocarbon, an olefin, and a metal oxide. Kinetic and stereochemical studies indicate that a cyclic, unimolecular six-center transition state is involved. This reaction represents the conversion of an alcohol to an olefin in a stereochemical syn manner and compares favorably as an alternative to the Chugaev and acetate pyrolysis reactions. © 1979, American Chemical Society.
