Special Issue Information

Dear Colleagues,

Reactions of hydrocarbons and alcohols occurring with the functionalization of C-H bonds can be catalyzed by metal complexes. These transformations are widely applied for organic synthesis, water photo-oxidation, the fixation of CO, CO2 and N2, etc. The efficient and selective functionalization of C–H bonds in saturated and aromatic hydrocarbons is one of the very important goals of organic chemistry. Many reactions of various organic compounds occur via C–H bond functionalization, that is, replacing the hydrogen atom by any other group. All these processes lead to the formation of extremely valuable chemical products. New catalytic systems based on metal complexes have been discovered during the last decades, which allow us to introduce various groups into aromatic and even saturated hydrocarbons and their derivatives, as well as other C–H compounds (see, for example, A. E. Shilov, G. B. Shul’pin, “Activation and Catalytic Reactions of Saturated Hydrocarbons in the Presence of Metal Complexes”, Kluwer Academic Publishers, Dordrecht/Boston/London/Moscow 2002; G. B. Shul’pin, “New Trends in Oxidative Functionalization of Carbon–Hydrogen Bonds: A Review”, Catalysts 2016, 6(4), 50; F. Roudesly, J. Oble, G. Poli, “Metal-catalyzed CH activation/functionalization: The fundamentals”, J. Mol. Catal., A: Chem. 2017, 426, 275–296; D. S. Nesterov, O. V. Nesterova, A. J. L. Pombeiro, “Homo- and heterometallic polynuclear transition metal catalysts for alkane C-H bonds oxidative functionalization: Recent advances”, Coord. Chem. Rev. 2018, 355, 199–222; Alkane Funcionalization, Eds. A. J. L. Pombeiro, M. F. C. Guedes da Silva, J. Wiley & Sons Ltd. Hoboken/Chichester, 2019.) and oxidize alcohols into aldehydes, ketones and acids.

Full comprehensive and mini-reviews covering various fields of catalytic transformations and highlighting specific problems, describing new unusual catalysts, new unusual solvents, new methods of inducing reactions (by light irradiation, etc.), will be very helpful for the reader. The description of new methods applied to light alkanes, including methane. will be especially intriguing.

Abstract
Self-assembly of copper(II)phenylsilsesquioxane assisted by the use of 1,10-phenanthroline (phen) results in isolation of two unusual cage-like compounds: (PhSiO1,5)12(CuO)4(NaO0.5)4(phen)4 1 and (PhSiO1,5)6(PhSiO1,5)7(HO0.5) [...] Read more.
Self-assembly of copper(II)phenylsilsesquioxane assisted by the use of 1,10-phenanthroline (phen) results in isolation of two unusual cage-like compounds: (PhSiO1,5)12(CuO)4(NaO0.5)4(phen)4 1 and (PhSiO1,5)6(PhSiO1,5)7(HO0.5)2(CuO)5(O0.25)2(phen)3 2. X-Ray diffraction study revealed extraordinaire molecular architectures of both products. Namely, complex 1 includes single cyclic (PhSiO1,5)12 silsesquioxane ligand. Four sodium ions of 1 are additionally ligated by 1,10-phenanthrolines. In turn, “sodium-less” complex 2 represents coordination of 1,10-phenanthrolines to copper ions. Two silsesquioxane ligands of 2 are: (i) noncondensed cubane of a rare Si6-type and (ii) unprecedented Si7-based ligand including two HOSiO1.5 fragments. These silanol units were formed due to removal of phenyl groups from silicon atoms, observed in mild conditions. The presence of phenanthroline ligands in products 1 and 2 favored the π–π stacking interactions between neighboring cages. Noticeable that in the case of 1 all four phenanthrolines participated in such supramolecular organization, unlike to complex 2 where one of the three phenanthrolines is not “supramolecularly active”. Complexes 1 and 2 were found to be very efficient precatalysts in oxidations with hydroperoxides. A new method for the determination of the participation of hydroxyl radicals has been developed.
