- Arylation of n-octylsilane with 2-iodo-5-methyl thiophen using palladium catalyst through coupling reaction to obtain various arylation product has been carried out. Product of arylation was purified using silica column chromatography with ethyl acetate as eluent and was characterized using mass spectroscopy, 1H, 13C and DEPT 135 NMR spectroscopy. The results showed that product of arylation was colorless oil with m/z 432 namely tris(5-methyl-2-thiophen)octylsilane. The spectrum of 1H NMR resulted seven equivalent protons. The measurement using 13C NMR resulted thirteen equivalent carbons, which was confirmed using DEPT-135. The results of characterization using mass spectroscopy and NMR spectroscopy (H and C) showed that the product of synthesis was tris(5-methyl-2-thophen)octylsilane. Keywords : arylation, n-octylsilane, 2-iodo-5-methyl thiophen, palladium.
