Synthesis and optoelectronic properties of some new thiahelicenes

(Chemical Equation Presented) New symmetrical helically chiral penta- and heptacyclic aromatic systems containing two thiophene rings have been prepared, in good yields, under mild conditions using a photochemical route. Optoelectronic properties of these helically aromatic thia-systems were determined and exhibit interesting behavior. Copyright Taylor & Francis Group, LLC.

Flash vacuum pyrolysis of stabilised phosphorus ylides. Part 16. Model studies for the construction of conjugated polymers

Reaction of a range of bis(ylides) with acid chlorides has been used to prepare the bis(oxoylides) 11-15. Similarly a range of simple ylides react with bis(acid chlorides) to give bis(oxoylides) 19-27 with the isomeric structure. Flash vacuum pyrolysis (FVP) of one example of the first type results in extrusion of Ph3P rather than the expected Ph3PO while six examples of the second type do extrude Ph3PO upon FVP at 500 °C to afford the bis(alkynes) 28. Examples of the corresponding bis(tributylphosphonium ylides) have also been prepared but attempts to construct a tetrakis(oxoylide) 31 using a stepwise approach were unsuccessful. Fully assigned 13C NMR spectra are presented for six of the bis(oxoylides).
