Among the topics are the copper-catalyzed formation of carbon-phosphorous bonds with aryl halides, insights into the mechanism of modern Ullmann-Goldberg coupling reactions, copper-catalyzed alkynylation and alkenylation reactions of alkynyl derivatives, applying copper-mediated carbon-nitrogen bond formation in complex molecule synthesis, and reusable catalysts for copper-mediated cross-coupling reactions under heterogeneous conditions.

The controlled decoration of surfaces and design of bio-interfaces are exemplified by the preparation of SAMs containing azido groups on well-defined electrode surfaces for reaction with alkynyl substrates, and immobilization of surface arrays of acetylene-containing oligonucleotides on to azide functionalized SAMs on gold.
