実験手順
4.00 g of 4-ethynyl-4-methoxy-4′-propylbicyclohexyl, 5.04 g of 4-ethynyl-4,4′-dipentylbicyclohexyl, 10.65 g of copper(II) acetate monohydrate and 0.145 g of copper(I) iodide are refluxed overnight in a mixture of 25 ml of pyridine and 25 ml of methanol. Conventional work-up gives a mixture of the three coupling products 4-[4-(4,4′-dipentylbicyclohexyl-4-yl)buta-1,3-diynyl]-4-methoxy-4′-propylbicyclohexyl (C 76 N 136 I, Δε=0.95, Δn=0.006), 4-[4-(4,4′-dipentylbicyclohexyl-4-yl)buta-1,3-diynyl]-4,4′-dipentylbicyclohexyl and 4-[4-(4-methoxy-4′-propylbicyclohexyl-4-yl)buta-1,3-diynyl]-4-methoxy-4′-propylbicyclohexyl (C 121 N (80) I, Δε=−1.77, Δn=−0.002), which can easily be separated by chromatography.
