Special Issue Information

Dear Colleagues,

Palladium-catalyzed reactions are of vital importance in organic synthesis. Palladium catalysts have played a fundamental role in the development of a wide variety of transformations due to its versatility and high functional group tolerance. Indeed, nowadays, palladium-catalyzed reactions are routinely employed as powerful synthetic tools, both in academia and industry. Particularly interesting are the recent advances in new catalyst development, which have enabled to perform difficult transformations with unactivated substrates using low catalyst loadings under mild and green reaction conditions.

After the 2014 and 2016 editions, this Special Issue on Palladium Catalysts is already becoming a tradition in Molecules and we are delighted to launch the 2018 edition. This Special Issue will mainly focus on the latest advances and novel trends in the field of palladium catalysts, ranging from basic research and characterization studies to the development of highly active catalysts and their application in different redox processes, cross-coupling, as well as C–H activation reactions.

Abstract
Highly selective C(sp2)–C(sp2) cross-coupling of dihalogenated hydrocarbons comprising C(sp2)–Br and C(sp3)–Cl bonds with arylboronic acids is reported. This highly selective coupling reaction of the C(sp2)–Br bond is successfully achieved using Pd(OAc)2 and

Highly selective C(sp2)–C(sp2) cross-coupling of dihalogenated hydrocarbons comprising C(sp2)–Br and C(sp3)–Cl bonds with arylboronic acids is reported. This highly selective coupling reaction of the C(sp2)–Br bond is successfully achieved using Pd(OAc)2 and PCy3·HBF4 as the palladium source and ligand, respectively. A series of chloromethyl-1,1′-biphenyl compounds are obtained in moderate-to-excellent yields. Moreover, this protocol can be extended to the one-pot dual arylation of 1-bromo-4-(chloromethyl)benzene with two arylboronic acids, leading to diverse unsymmetrical 4-benzyl-1,1′-biphenyl derivatives.

Monitoring reaction paths is not only a fundamental scientific issue but also helps us to understand and optimize the catalytic process. Infrared (IR) and Raman spectroscopies are powerful tools for detecting particular molecules or intermediate products as a result of their ability to provide the molecular “finger-print”. However, theoretical modeling for the vibrational spectra of molecular adsorbates on metallic surfaces is a long-standing challenge, because accurate descriptions of the electronic structure for both the metallic substrates and adsorbates are required. In the present work, we applied a quasi-analytical IR and Raman simulation method to monitor the dehydrogenation of propane towards propylene on a Pd-doped Cu(111) surface in real-time. Different Pd ensembles were used to construct the single-atom catalyst (SAC). We found that the number of sublayer Pd atoms could only affect the intensity of the peak rather than the peak position on the vibrational spectra. However, with the dehydrogenation reaction proceeding, both IR and Raman spectra were changed greatly, which indicates that every reaction step can be distinguished from the point of view of vibrational spectroscopies. Additionally, we found that the catalytic process, which starts from different initial states, shows different spectral profiles. The present results suggest that the vibrational spectroscopies obtained by the high-precision simulations pave the way for identifying different catalytic reaction paths. Full article
