Consecutive modular ligation as an access route to palladium containing polymers

The btp [2,6-bis(1,2,3-triazol-4-yl)pyridine] binding motif: a new versatile terdentate ligand for supramolecular and coordination chemistry

“…The chloroplatinum(II) complexes were found to be non-luminescent in solution at room temperature, however, the alkynylplatinum(II) complexes were observed to be luminescent, displaying large Stokes shifts, , the only Pd(II) complex of a discrete btp system in the literature, of which a crystal structure was also obtained. 123 …”

“…161 Polymer 63 was prepared via a CuAAC reaction, yielding a soluble material which was employed as a suitable support for metal loading with Pd(II), where 1 H NMR spectroscopy and elemental analysis were used as evidence of successful loading (the same research also yielded products with different spacers between the btp motifs, which were not further investigated). 123 Organic phosphonates can be covalently attached to the surface of the inorganic species g-zirconium phosphate by topotactic exchange, and as such, a btp-based phosphonate ligand 44 was prepared, with a view to producing a solid host which could efficiently sensitise the emission of Ln(III) ions (Eu(III) and Tb(III), specifically) via the 'antenna effect'. 94 Compound 44 was also introduced into the inorganic framework by simply suspending the g-zirconium phosphate colloidally in a water-acetone mixture at 80 1C for a few minutes with the ligand.…”

NHC Polymeric Particles Obtained by Self-Assembly and Click Approach of Calix[4]Arene Amphiphiles as Support for Catalytically Active Pd Nanoclusters

“…Amongst N-heterocyclic carbenes, polytopic ligands featuring more than one NHC unit are of high demand, as they impact the stability of the final metal complex, owing to their chelating abilities [8,9]. A special case of polytopic NHC ligands are polymeric NHCs [10], which can be obtained by grafting on a polymeric support [11] or by copolymerization of imidazolium-containing monomer to give self-supported polymeric NHC [12][13][14]. Such polymeric NHCs combine the activity and selectivity of homogeneous catalysts, with the possibility of reuse, which is characteristic for heterogeneous ones.…”

Synthesis and Structure of Palladium Complexes [Ph3PMe]+[PdBr3(DMSO)]– and [Ph3P(CH2)6PPh3]2+[PdBr3(Et2SO)]–2

“…Комплексные соединения палладия с анионами типа [PdHal 3 (dmsoS)] -Hal = Cl, Br описаны в литературе [1][2][3][4][5][6][7][8][9][10][11], однако подобные комплексы с анионами, содержащими координированные молекулы диэтилсульфоксида структурно не охарактеризованы. Известны единичные примеры комплексов платины (II) с анионом [PtHal 3 L] -, где L -S-координированные молекулы сульфоксидов, отличные от диметилсульфоксида, такие как L -диэтилсульфоксид, Hal = Cl [12], Br [13]; L -ди-n-пропилсульфоксид, Hal = Cl, Br; L -тетраметиленсульфоксид, Hal = Cl [14].…”
