TEMPO in metal complex catalysis

Molecular Cage Promoted Aerobic Oxidation or Photo-Induced Rearrangement of Spiroepoxy Naphthalenone

“…With the Pd salt (TMEDA)Pd(NO3)2 as catalyst, product 3 could only be obta a 39% yield (entry 5). Considering previous reported work [39,[45][46][47][48][49][50], we propo redox-active nature of cage 1 plays a key role in this aerobic Wacker oxidation pro…”

Crystal structure and Hirshfeld surface analysis of dimethyl 5-[2-(2,4,6-trioxo-1,3-diazinan-5-ylidene)hydrazin-1-yl]benzene-1,3-dicarboxylate 0.224-hydrate

“…All the reported hydrazone ligands are stabilized in the hydrazone form by intramolecular resonance-assisted hydrogen bonding (RAHB) between the hydrazone N-NH-fragment and the carbonyl group, giving a six-membered ring (Gurbanov et al, 2020a;Kopylovich et al, 2011a,b;Mizar et al, 2012). The use of multifunctional ligands in coordination chemistry is a common way to increase the water solubility of metal complexes, which is important for catalytic applications in aqueous medium (Ma et al, 2020(Ma et al, , 2021Mahmudov et al, 2013;Sutradhar et al, 2015Sutradhar et al, , 2016. Moreover, non-covalent interactions such as hydrogen, halogen and chalcogen bonds as well as -interactions or their cooperation are able to contribute to synthesis and catalysis and improve the properties of materials (Gurbanov et al, 2020b;Karmakar et al, 2017;Khalilov et al, 2018a,b;Mac Leod et al, 2012;Shikhaliyev et al, 2019;Shixaliyev et al, 2014).…”

Crystal structure and Hirshfeld surface analysis of (3aR,4S,7S,7aS)-4,5,6,7,8,8-hexachloro-2-{6-[(3aR,4R,7R,7aS)-4,5,6,7,8,8-hexachloro-1,3-dioxo-1,3,3a,4,7,7a-hexahydro-2H-4,7-methanoisoindol-2-yl]hexyl}-3a,4,7,7a-tetrahydro-1H-4,7-methanoisoindole-1,3(2H)-dione

“…For this reason, many approaches have been developed for their efficient and versatile synthesis (Gurbanov et al, 2017(Gurbanov et al, , 2018aMa et al, 2017a,b). On the other hand, N-heterocycles or N-ligands can also be used as precursors in the synthesis of coordination compounds (Ma et al, 2020(Ma et al, , 2021Mahmudov et al, 2013), and as building blocks in the construction of supramolecular structures as they have both hydrogen-bond donor and acceptor capabilities (Gurbanov et al, 2020a;Kopylovich et al, 2011a,b;Asgarova et al, 2019). In fact, attachment of suitable functional groups to N-ligands can improve their solubility and the catalytic activity of the corresponding coordination compounds (Mizar et al, 2012;Gurbanov et al, 2020b;Khalilov et al, 2011Khalilov et al, , 2018aMaharramov et al, 2019;Shikhaliyev et al, 2019;Shixaliyev et al, 2014).…”
