The study presents a novel and efficient method for synthesizing N,N'-substituted symmetrical diamines using diazidoalkanes and dichloroboranes. The researchers combined readily available starting materials, diazidoalkanes and dichloroboranes, in a one-pot procedure to produce the desired diamines in high yields. This method avoids the formation of polyalkylated by-products, which are commonly observed in reactions involving amines and alkyl halides. The synthesized diamines were characterized by 1H and 13C NMR spectroscopy, elemental analysis, and mass spectrometry. The study also extended this approach to the synthesis of thermine, a tetramine with biological significance, demonstrating the versatility and applicability of this synthetic route. The method offers distinct advantages over previous procedures, including the use of readily available starting materials, high yields, and simplified purification steps.
