Strategies towards functionalised electronically conducting organic copolymers: Part 2. Copolymerisation

Here we discuss the application of X-ray photoelectron spectroscopy and absorbance-reflectance FT-IR spectroscopy to establish and quantify reactivity relationships between a range of thiophene and pyrrole monomers. In particular we investigate the application of these techniques to the characterisation of conducting polymer materials grown potentiostatically from solutions containing a binary mixture of monomers. Our data have shown that XPS is especially effective in determining polymer composition and the linear correlation between this and solution composition has enabled prescriptive synthesis of copolymer materials from the different combinations of monomers described here. This technique is much more convenient and more reliable than elemental analysis. In contrast we show that FT-IR studies, whilst providing a useful qualitative guide to the functional group content of the material, do not facilitate detailed quantitative analysis because of large intrinsic errors.

Regioselective Synthesis of Acylpyrroles

The regioselective synthesis of several pyrrole derivatives is described.AlCl3-catalyzed acylation reactions of 1-(phenylsulfonyl)pyrrole (1) give 3-acyl derivatives, whereas the corresponding BF3*OEt2-catalyzed reactions give 2-acyl derivatives predominantly.Mild alkaline hydrolysis gives the corresponding acyl-1H-pyrroles in excellent yields.AlCl3-catalyzed reactions of 1 with 1,1-dichloromethyl methyl ether and oxalyl chloride give 1-(phenylsulfonyl)-2-formylpyrrole (6) and 1-(phenylsulfonyl)-2-(chlorocarbonyl)pyrrole (7), respectively. 3-Pyrrolylacetic acid (10) was prepared by thallium(III) nitrate promoted rearrangement of 1-(phenylsulfonyl)-3-acetylpyrrole (2a).Trifluoroacetic anhydride catalyzed cyclization of 4-butyric acid (14) gives 1-(phenylsulfonyl)-7-oxo-4,5,6,7-tetrahydroindole (17).Attempts to cyclize 14 at the 4-position have been unsuccessful.
