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 present invention provides methods of designing molecularly imprinted polymers (MIPs) which have applications in extracting bioactive compounds from a range of bioprocessing feedstocks and wastes. The present invention is further directed to MIPs designed by the methods of the present invention.

A nanohybrid of Pd on GO functionalized with N and S has been fabricated, and demonstrated as an efficient catalyst for Heck coupling with a substantially low catalytic loading (0.02 mol%).
Oligomeric Silsesquioxane (IC-POSS) based poly (Acrylamide-co-Hydroxy ethyl methacrylate) as a novel nanohybrid catalyst were synthesized and characterized. This catalyst was found to be an efficient and reusable heterogeneous catalyst for the Heckreaction using water as the solvent in the absence of a phosphine ligand and phase transfer catalyst.Graphical Abstract
