WebBoord olefin synthesis. The Boord olefin synthesis is an organic reaction forming alkenes from ethers carrying a halogen atom 2 carbons removed from the oxygen atom (β-halo-ethers) using a metal such as magnesium or zinc. The reaction, discovered by Cecil E. Boord in 1930 [1] is a classic named reaction with high yields and broad scope. [2] WebThe Bouveault aldehyde synthesis (also known as the Bouveault reaction) is a one-pot substitution reaction that replaces an alkyl or aryl halide with a formyl group using a N, N -disubstituted formamide. [1] [2] For primary alkyl halides this produces the homologous aldehyde one carbon longer.
