We can share the view of some authors (Fenchel et al., 1998) that this theory may serve a plausible explanation of thioester world as precursor for the present RNA world. Furthermore, it is attractive in a number of respects too. One has to mention the development of very early, global scale geochemical cycling of carbon, sulfur, and iron. It would present the early interactions between atmosphere and biochemical processes, like thioester-bounded hydrogen production contribution to the formation of reducing species that were critical for any atmospheric organic synthesis. 

In this article we have attempted not only to point out some of the most useful methods for the synthesis of alkylthiophenes but also to show the value of synthesis of authentic standards in identifying the components of the organic extracts of sediments. It is only after the correct identification of the structures that more detailed conclusions regarding organic geochemical problems can be...
