Document Type and Number:
Japanese Patent JP2007084447
Kind Code:
A
Abstract:

To provide a 10-halo-5,9-dimethyldecane as an intermediate in the manufacture of 5,9-dimethyldecane, and a method for industrially efficiently manufacturing a 5,9-dimethylalkane.

A Grignard reagent of a 7-halo-3-methylheptane (wherein halo is Cl or Br) as a starting material is subjected to a cross-coupling reaction with 1-bromo-3-chloro-2-methylpropane or 1,3-dibromo-2-methylpropane to give the 10-halo-5,9-dimethyldecane (wherein halo is Cl or Br). A Grignard reagent of the thus-obtained 10-halo-5,9-dimethyldecane as a common intermediate is subjected to a cross-coupling reaction with an alkyl bromide or an alkyl iodide to give the 5,9-dimethylalkane.
