This work describes the development of easy-to-prepare cobalt nanoparticles (NPs) in solution as promising alternative catalysts for alkene hydrosilylation with industrially relevant tertiary silane 1,1,1,3,5,5,5-heptamethyltrisiloxane (MDHM). The Co NPs demonstrated high activity when used at 30 °C 3.5-7 h toluene, catalyst loadings 0.05-0.2 mol %, without additives. Under these mild conditions, a set terminal alkenes were found to react MDHM, yielding exclusively anti-Markovnikov product...
Abstract We report an unprecedented selective cleavage of aromatic C−C bonds through the insertion well‐defined iridium complexes into ring simple alkylarenes. The occurs at 50–100 °C without activation weaker C−H and gives unique metallacycles in high yields. Key to success this approach is metal‐induced deformation arene ring, which creates temporary strain promotes direct metal otherwise inert bonds.
Regioselective metal insertion into aromatic C-C bonds is a long-standing problem critical for development of new arene functionalizations and cleaner conversion fossil fuel value-added chemicals. We report reversible iridium the η4-bound methyl arenes to give eight-membered diiridium metallacycles with yields up 99%. While at 50-100 °C reaction mixture isomers corresponding in both unsubstituted Me-substituted ring bonds, 150 single isomer dominates. Kinetic DFT studies suggest that...
The catalytic performances in hydrosilylation of alkenes strongly depend on the structure O-functionalized NHC Rh(<sc>i</sc>) complexes.
Herein, we report the successful characterization of sulfur vacancies in ZnS nanoplatelets by in-depth high-field and DNP-enhanced solid-state NMR 33S 67Zn nuclei DFT modeling. This two-dimensional 1 nm-thick nanomaterial was obtained reacting a dicyclohexyl zinc complex, ZnCy2, with (TMS)2S as S source under mild conditions (45 °C) dodecylamine. The joint experimental theoretical studies on these evidenced that large fraction Zn atoms are located near surface covered dodecylamine deviation...
Aromatic C–H activation in alkylarenes is a key step for the synthesis of functionalized organic molecules from simple hydrocarbon precursors. Known examples such activations often yield mixtures products resulting least hindered bonds. Here we report highly selective ortho-C–H by iridium complexes. We demonstrate that capacity alkyl substituent to override typical preference metal-mediated aromatic bonds results transient insertion into benzylic bond. This enables fast bond, followed...

Semiconducting heterostructures are considered promising candidates for meeting specific environmental challenges, such as greener or decarbonated production of energy. However, optimizing the performance these hybrid systems largely depends on fine understanding mechanisms by which they formed in relation to their mode preparation. We report herein synthesis nanosized semiconducting ZnS@ZnO shell-core nature; this is from well-controlled preformed ZnO nanoparticles (NPs) modified via anion...
