starting-materials, obtainable free from near homologues, to compounds of doubled chain length have been explored as approaches to the synthesis of n-paraffins and of terminally mono- or bi-functional derivatives. Acetylene alkylation routes lead to problems with protecting groups, but the use of the Wittig reaction provides a method of moleculardoubling convenient for repeated use, with the formation of chain-lengths

A convenient General synthesis, applicable to alkanes and terminally mono- and di-substituted alkanes of any chain length, is described; cyclododecanone is used as the starting material, and the C12 chain is doubled in length as often as required and adjusted first to a multiple of 12, and than to any desired length.
