The Synthesis of Long-chain Unbranched Aliphatic Compounds by Molecular Doubling

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 then to any desired length.
Studies on the Synthesis of Linear Aliphatic Compounds. Part. 3. The Synthesis of Paraffins with Very Long Chains

The approach derived in Part 2 has been modified to increase the purity and yield of intermediates.The C12 starting materials have been doubled in chain length five times, and by using components of similar or different chain length in Wittig condensations ω-halogeno-acetals with 12n carbon atoms have been made up with n up to 32.They have been converted into paraffins with 102, 104, 150, 198, 246, 294, and 390 carbon atoms.Those paraffins with 150 or more carbon atoms show chain-folding in the crystalline state; this observation is contributing to the understanding of chain-folding behaviour long known in linear polyethylene but hitherto unknown in essentially pure paraffins.
