An alternative heterogeneously palladium catalysed procedure for the synthesis of functional stilbenes and bibenzyls is reported. Starting from aryl bromides and using simple commercially available Pd/C catalyst at a low catalytic rate (1 mol%), stilbenes are obtained with 30-100% GC-yields and bibenzyls are produced in a one-pot fashion with 27-100% GC-yields. The procedure showed, however, some limitations when applied to strongly deactivated aryl bromides that could be in some extent overcome by using corresponding iodo derivatives.

The synthesis of a series of liquid crystalline side-chain polyacrylates in which the mesogenic group is 1-(4-benzoyloxyphenyl)-2-(4'-cyanophenyl)ethane is reported.Methylenic spacer groups of different lengths have been used.Polymers were prepared by radical polymerization (AIBN as initiator) of the corresponding acrylates.The liquid crystalline nature of these polymers was established by calorimetric measurements, optical texture observations and X-ray investigations.For the polymer where n=6, the unusual I-N-SAd-Nre sequence was observed.
