Catalyzed Reactions

Palladium-catalyzed bond-forming reactions, such as the ­Suzuki–Miyaura and Mizoroki–Heck reactions, are some of the most broadly utilized reactions within the chemical industry. These reactions frequently employ hazardous solvents; however, to adhere to increasing sustainability pressures and restrictions regarding the use of such solvents, alternatives are highly sought after. Here we demonstrate the utility of dimethyl isosorbide (DMI) as a bio-derived solvent in several benchmark Pd-catalyzed reactions: Suzuki–Miyaura (13 examples, 62–100% yield), Mizoroki–Heck (13 examples, 47–91% yield), and Sonogashira (12 examples, 65–98% yield).

Catalyzed Reactions

Palladium-catalyzed reactions such as Sonogashira coupling, Suzuki coupling, Stille coupling, Heck reactions, and Glaser-Hey oxidation were used to construct porphyrin modules of nano-scale molecular size in recent years. Recent developments in the supramolecular assembly of porphyrins and Pd (II) and in the organopalladium complexes of various porphyrins are also summarized.

Catalyzed Reactions

Palladium-catalyzed cross-couplings and related reactions have enabled many transformations essential to the synthesis of pharmaceuticals, agrochemicals, and organic materials. A related family of reactions that have received less attention are decarboxylative functionalization reactions. These reactions replace the preformed organometallic precursor (e.g., boronic acid or organostannane) with inexpensive and readily available carboxylic acids for many palladium-catalyzed reactions. This review focuses on catalyzed reactions where the elementary decarboxylation step is thought to occur at a palladium center. This review does not include decarboxylative reactions where decarboxylation is thought to be facilitated by a second metal (copper or silver) and is specifically limited to (hetero)arenecarboxylic acids. This review includes a discussion of oxidative Heck reactions, protodecarboxylation reactions, and cross-coupling reactions among others.1 Introduction2 Oxidative Heck Reactions3 Protodecarboxylation Reactions4 Cross-Coupling Reactions5 Other Reactions6 Conclusion

Catalyzed Reactions

Since the late 1980s, the scientific community has been attracted to microwave energy as an alternative method of heating, due to the advantages that this technology offers over conventional heating technologies. In fact, differently from these, the microwave heating mechanism is a volumetric process in which heat is generated within the material itself, and, consequently, it can be very rapid and selective. In this way, the microwave-susceptible material can absorb the energy embodied in the microwaves. Application of the microwave heating technique to a chemical process can lead to both a reduction in processing time as well as an increase in the production rate, which is obtained by enhancing the chemical reactions and results in energy saving. The synthesis and sintering of materials by means of microwave radiation has been used for more than 20 years, while, future challenges will be, among others, the development of processes that achieve lower greenhouse gas (e.g., CO2) emissions and discover novel energy-saving catalyzed reactions. A natural choice in such efforts would be the combination of catalysis and microwave radiation. The main aim of this review is to give an overview of microwave applications in the heterogeneous catalysis, including the preparation of catalysts, as well as explore some selected microwave assisted catalytic reactions. The review is divided into three principal topics: (i) introduction to microwave chemistry and microwave materials processing; (ii) description of the loss mechanisms and microwave-specific effects in heterogeneous catalysis; and (iii) applications of microwaves in some selected chemical processes, including the preparation of heterogeneous catalysts.
