Reaction Steps

4-Cyanophenylboronic acid (7 g, 0.0476 m) was stirred and refluxed for 60 hours under nitrogen with 4-n-heptylthiobromobenzene (12.4 g, 0.0433 m), TTPP (0.9 g, 0.000783 m), 2 molar aqueous sodium carbonate (41 mls). toluene (86 mls) and industrial methylated spirit (20.5 mls). The mixture was then separated and extincted with toluene (2×100 mls) washed with water (100 mls) and dried over magnesium sulphate. The solvents were then evaporated off to give a brown solid products which was purified by column chromatography and recrystallisation from industrial methylated spirit. 4-Cyano-4'-heptylthiobiphenyl was produced (4.1 g, 100% HPCL, 30% yield melting point 64.4° C.).
