    • The LDI-TOF spectra of 6,7, and other related compounds show, besides the molecular ion peak (low intensity), patterns of signals with a Gaussian type distribution at somewhat lower masses (relatively high intensity). The peaks of these patterns are separated by a constant m/e = 28 Da. The reason for this finding is not yet understood. A possible systematic distribution of molecular finding caused by an inadvertent employment of reagents with an even distribution of methylene groups in the alkyl chains is unlikely. The alkyl chains are introduced into the whole sequence as bromides and alcohols (see Refs. [3d, 5]), the purity of which was greater than 98% (checked by (GC)).
