Participants

Reaction Steps

8.12 g (0.032 mol) of 4′-But-3-enyloxy-biphenyl-4-carbonitrile is dissolved in 80 mL of dry toluene and 21.50 g (0.16 mol) of 1,1,3,3-Tetramethyl-disiloxane is added. Dry air bubbled through the solution for 2 min and few drops of platinium(0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex in xylene are added. After stirring at room temperature for 20 h with exclusion of moisture, the solvent and excess of 1,1,3,3-Tetramethyl-disiloxane are distilled off under reduced pressure. The residue purified by column chromatography on silica gel using a mixture of CH2Cl2/pentane (75/25) as eluent gives a colourless oil (10.67 g, 84% yield).
