Special precautions had to be taken to avoid undesired polymerization of the styryl-substituted compounds during synthesis and workup. Only sufficiently dilute solutions were heated; crude products were purified immediately by flash-column chromatography; purified compounds were stored in a refrigerator, with exclusion of light

We also tried to synthesize a para-substituted spacer molecule by etherification of 4-hydroxy-benzyl alcohol and 4-vinyl-benzyl chloride, followed by Appel reaction. However, the resulting benzyl bromide could not be isolated due to hydrolysis during workup

3 as base and acetone as solvent did not suppress silyl migration and gave the coupling products in comparable yields after heating for 72 h at 50-60°C. In order to reduce the risk of racemization of BINOL during the several days of coupling conditions at elevated temperatures, we decided to perform the coupling step under the conditions described above (NaH, DMF, RT)
