20.500.12556/RUL-125377 Pyridine wingtip in ▫$[Pd(Py-tzNHC)_2]^{2+}$▫ complex is a proton shuttle in the catalytic hydroamination of alkynes The cationic palladium(II) complex 1 of pyridylmesoionic carbene ligand catalyzes Markovnikov-selective intermolecular hydroamination between anilines and terminal alkynes into the corresponding imines. The reaction proceeds at room temperature, in the absence of additives, with exquisite selectivity and diverse functional group tolerance. The key intrinsic feature of the catalyst is the pyridine wingtip confined to the proximity of the alkynophilic metal active site, which mimics the function of enzyme-like architectures by assisting entropically favored proton transfers. catalysis palladium hydroamination metal-ligand cooperation proton transfer DFT hydrocarbons chemical reactions reaction mechanisms metals pyridines kataliza paladij hidroaminiranje sodelovanje kovina-ligand prenos protona DFT hidrokarbonati kemijske reakcije mehanizmi reakcij kovine piridini true false true Angleški jezik Slovenski jezik Članek v reviji 2021-03-12 14:25:42 2021-03-12 14:25:42 2022-09-05 03:50:29 0000-00-00 00:00:00 2020 0 0 Str. 2157-2161 iss. 6 Vol. 22 20 Mar. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 547.82:546.98 1523-7060 10.1021/acs.orglett.0c00203 1538522051 1916442 RAZ_Virant_Miha_2020.pdf RAZ_Virant_Miha_2020.pdf 1 929D5DEA8B35D00FDA7B695116819BB9 60971a2d675cb6720fcb7fefef5584278ca8001b195f5f20004f640594451efd b323910a-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141081 https://pubs.acs.org/doi/10.1021/acs.orglett.0c00203 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=141080 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
