Abstract
Telah disintesis senyawa heterosiklik aromatik lingkar lima turunan tiofena, yaitu 3-desiloksitiofena yang dapat digunakan sebagai monomer dari polimer konduktif. Prediksi mekanisme sintesis berdasarkan pada reaksi substitusi nukleofilik aromatik heterosiklik. Sintesis dilakukan dalam sistem refluks selanjutnya senyawa n-heksana : kloroform dengan perbandingan 1 : 2 digunakan sebagai eluen dalam kromatografi lapis tipis dan kolom. Analisis senyawa yang dilakukan dengan metode spektroskopi NMR dan FTIR menunjukkan bahwa hasil reaksi diduga berupa senyawa 3-desiloksitiofena.

In this work, 3-decyIoxythiophene, the five membered aromatic heterocyclic compound had been successfully synthesized. This compound could be considered as a monomer of organic conducting polymer. The synthesis mechanism of 3-decyloxythiophene was predicted based on aromatic nucleophilic substitution reaction of heterocyclic compound. Synthesis of the 3-decyloxythiophene was brought up by using a reflux system, and followed by separation of solvent and byproduct. Thin layer chromatography and column chromatography were used to analyze the result of the reaction, with the ratio of n-hexane: chloroform = 1: 2 as the eluent. Moreover, Nuclear Magnetic Resonance and Fourier Transforms Infrared Spectroscopy were used to show the structure of the compounds after reaction. The result show that 3-decyloxythiophene had been formed.
