Coupling of Butyl Bromide on Hot Magnesium.
A report of the formation of octane when butyl bromide is passed over magnesium turnings at high temperatures should be amended. Such coupling does take place over pure magnesium at more moderate temperatures but yields 3-methylheptane and sec-butyl bromide in addition to octane. Sec-butyl bromide itself forms no coupling product under such conditions but admixed with butyl bromide markedly increases the 3-methyl-heptane:octane ratio in the product.
