We combine top-down and bottom-up nanolithography to optimize the coupling of small molecular spin ensembles $1.4$ GHz on-chip superconducting resonators. Nanoscopic constrictions, fabricated with a focused ion beam at central transmission line, locally concentrate microwave magnetic field. Drops free-radical molecules have been deposited from solution onto circuits. For smallest ones, were delivered relevant circuit areas by means an atomic force microscope. The number spins $N_{\rm eff}$...
A CNC based rhodium complex is an efficient catalyst for formic acid dehydrogenation under solventless conditions.
High molecular weight polymers by rhodium-catalyzed Markovnikov-selective alkyne polyhydrothiolation.
The pincer ligand HN(CH2CH2PPh2)2 (1; PNHP) reacted with [{Ir(μ-X)(cod)}2] (X = Cl, OMe), affording complexes [fac-(PNHP)Ir(cod)]Cl (2) and [fac-(PNP)Ir(cod)] (3), respectively. X-ray molecular structure of 2 showed that the PNP coordinates in a facial fashion, N atom an axial site both P atoms coordinated equatorial plane. Compound 1 is able to protonate hydroxo bridges complex [{Ir(μ-OH)(coe)2}2] forming new amido [mer-(PNP)Ir(coe)] (4). Complex 4 extremely air sensitive compound, as...
The [Rh(μ-Cl)(IPr)(η2-coe)]2/pyridine system efficiently catalyzes the polyhydrothiolation of a series dialkynes with dithiols, producing sulfur-rich poly(vinylidene sulfide)s typical Mw in range 20.000–124.000 and vinylidene content 75–87%. A combination flexible aliphatic including 1,6-hexanedithiol 2,2′-(ethylendioxy)diethanethiol, rigid aromatic dithiol 4,4′-thiobisbenzenethiol, dialkynes, 1,3-diethynylbenzene 1,4-diethynylbenzene, propargyl ether 1,7-octadiyne, have been used to prepare...
Lutidine-based NHCs pincer precursors CNCMe and CNCMes were combined with [Rh(acac)(nbd)] (acac = acetylacetonate; nbd 2,5-norbornadiene) in the presence of Cs2CO3 to yield complexes [(CNC)MeRh(nbd)]PF6 (3) [(CNC)MesRh(NCMe)]PF6 (4), respectively. While 3, diolefin remains coordinated, 4, voluminous mesityl ligands induce decoordination, so acetonitrile stabilizes Rh(I) adduct which turn undergoes substitution reactions a number neutral produce cationic [(CNC)MesRh(L)]PF6 (L CO (5), PMe2Ph...
Reaction of an amido pincer complex [(CNC)*Rh(CO)] (1) (CNC* is the deprotonated form CNC) with carbon dioxide gave a neutral [(CNC-CO2)Mes*Rh(CO)] (2), which result C-C bond-forming reaction between arm CNC* ligand and CO2. The molecular structure 2 showed zwitterionic complex, where CO2 moiety covalently connected to former ═CH ligand. unusual 1 allowed us explore reactivity selected primary amines RNH2 (benzylamine ammonia), afforded cationic complexes [(CNC)MesRh(CO)][HRNC(O)O] (R = Bz...
