Among the templates d- cussed in these two volumes were convex and concave templates that mediate the formation of (macro)cyclic molecules and mechanically bound molecules withtheir intriguingintertwined topology.Also,three-dimensional templates that are used to imprint polymers and that organize compounds in the solid state for predestined reactions have been included in the earlier volumes. In the present volume, we extend thetemplate topologytosurfaces that act asmatricesforthecontrolledgrowthoftwo-dimensionalarrays.Naturally,the typical methods for the characterization of surfaces such as scanning probe microscopyare prominently represented in this volume. Differentlateralinteractionssuchascoordinativebondsorhydrogenbo- ing play a major role in assembling the 2D networks on surfaces in addition to the interaction of the samples with the underlying substrates. Many p- nomena that are also encountered in solution can be directly visualized on surfaces: Reversible self-assembly processes lead to the formation of large structures through multiple recognition of small building blocks and cul- nate in the engineering of crystals in two dimensions. Self-sorting processes drive the formation of highly ordered arrays through the geometric ?t of the available components. Either the surface itself is the template, for example, when clusters grow on metal oxide ?lms, or colloidal templates control the formationof macroporousnetworksonthe substrate. This volume highlightsa selection of actual complementary aspects of s- facetemplates.Webelievethatthescopeandthevarietyoftopicscoveredinthis volume will attract readers fromdifferent communities such as supramole- larchemistry,materialsciences,surfacechemistry,surfacephysicsandsurface technologyandwehopetheywillenjoythisnewvolumeonTemplatesinCh- istry.

Metal carbene complexes have made their way from organometallic curiosities to valuable reagents and catalysts. They offer novel synthetic opportunities in carbon carbon bond formation based on either carbene-centered reactions or on metal-templated processes which makes them indispensable in modern synthetic methodology. The most prominent metal carbenes are now either commercially available or easy to synthesize and handle by modern laboratory techniques. This volume organized in eight chapters written by the leading scientists in the field illustrates the theoretical background, non-classical nucleophilic and cycloaddition patterns, chromium-templated benzannulation and photo-induced reactions, rhodium-catalyzed carbene transfer as well as the principles and applications of olefin metathesis which coined the progress in synthetic methodology over the past decade. Designed for researchers in academia and industry as well as graduate students it presents the state-of-the-art potential of carbene complexes in modern organic synthesis.
