In the following book chapter [118] the last 10 years of research on (thio)urea organocatalysts are summarized considering catalyst design concepts, experimental details such as structure optimization studies, screening conditions, reaction conditions, the typical substrate and product spectrum of each procedure as well as proposed mechanistic scenarios for each published methodology (-150 articles). 

In 2005, Nagasawa and co-workers developed a new catalyst design concept leading to novel hydrogen-bonding bifunctional organocatalysts, which incorpo-...

Carbene ligands can replace phosphines dne to similar electronic properties. The development of NHC design concepts featnring different substituents and backbones eventually culminated in the most prominent derivative, the SIMes (SDVtes = A, A -bis[2,4,6-(trimethyl)phenyl]imidazolidin-2-ylidene) ligand that is nsed in the second and later also third generation catalysts (complexes 72, 73, 74b and 74c in Fig. 3.28) [105, 109, 114,116],... 

In this contribution, we describe the discovery and application of phenoxy-imine ligated early transition metal complexes (FI catalysts) for olefin polymerization, including the concept behind our catalyst design, the discovery and the polymerization behavior of FI catalysts, and their applications to new polyolefinic materials. 

Different design concepts have been proposed to match the severe requirements of catalytic combustors. A main classification criterion is based on fuel/air stoichiometry in the catalyst section, which has a dominant effect on the selection of catalytic materials and on the operating characteristics of the combustor. In this section, only configurations based on lean catalytic combustion will be described. The peculiar characteristics of rich catalytic combustion will be described in a separate section. 

The first design concept tried to exploit fully the potential of catalytic combustion by completing the process in a single catalyst section. In such a configuration, a...
