Polymer-supported reactions overview

Abstract An overview on the microwave-enhanced synthesis and decoration of the 2(lH)-pyrazinone system is presented. Scaffold decoration using microwave-enhanced transition-metal-catalyzed reactions for generating structural diversity, as well as the conversion of the 2(lH)-pyrazinone skeleton applying Diels-Alder reactions to generate novel heterocyclic moieties are discussed. The transfer of the solution phase to polymer-supported chemistry (SPOS) is also described in detail.

The design of bionanoreactors is based on encapsulation/insertion of active compounds (proteins, enzymes, mimics) inside polymeric supramolecular assemblies, such as dendrimers, capsules, and vesicles, in which they can act in situ while being protected from proteolytic attack [3,6]. These supramolecular assemblies should allow the passage of products or substrates to the inner spaces where the active compounds are located in order to support reactions confined within their structures. Various approaches to providing accessibility to the inner reaction space of the polymer assemblies are presented, even though not all have been used in the design of nanoreactors, in order to give an overview of the variety of solutions that can be expected to advance this field of science. 

Currently, low-temperature CO oxidation over Au catalysts is practically important in connection with air quality control (CO removal from air) and the purification of hydrogen produced by steam reforming of methanol or hydrocarbons for polymer electrolyte fuel cells (CO removal from H2). Moreover, reaction mechanisms for CO oxidation have been studied most extensively and intensively throughout the history of catalysis research. Many reviews [4,19-28] and highlight articles [12, 29, 30] have been published on CO oxidation over catalysts. This chapter summarizes of the state of art of low temperature CO oxidation in air and in H2 over supported Au NPs. The objective is also to overview of mechanisms of CO oxidation catalyzed by Au.
