1,3-Diphosphapropenes for novel chemistry of metal complexes

vic‐Dichlorodiphosphapropenes – Synthesis and Coordination Ability

“…[1] To date, diphosphapropenes Mes*P=C(X)-PR 2 (Mes* = supermesityl = 2,4,6-tri-tert-butylphenyl) (I) [2][3][4][5][6] and their oxidation products with sulfur, [5][6][7][8][9] and in a few cases with oxygen, [10] have been reported. Monocoordinate complexes with W(CO) 5 and chelates with W(CO) 4 of I were obtained and characterized for the systems with R 1 R 2 = Ph 2 and X = Cl, [2] Me, [3] SiMe 3 .…”

In silico modelling of chelate stabilized tetrylene derivatives

“…An appealing yet scarcely employed ligand is the diphosphaalkenyl derivative containing the P]C-P(Cl)]X moiety (X = S or O). 7,8 Due to its multiple connection sites, this electron-rich system can potentially stabilize the E(II) species. The presence of halogen substituents on one of the phosphorus atoms, or on the central carbon atom, makes such ligands as suitable building blocks for larger organometallic derivatives.…”

Magnetically modified Schiff base‐Pd complex: An efficient heterogeneous catalyst for Suzuki–Miyaura cross‐coupling and dyes degradation reaction

“…[1,18,19] For the Suzuki coupling reaction, different homogeneous and heterogeneous catalysts have previously been reported. [6,[20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] For example, Fe 3 O 4 /SiO 2 -NH 2 /SA/Pd showed good activity for Suzuki coupling reaction in toluene as a solvent, [32] Pd/FTO catalyst for conversion of iodobenzene to biphenyl employing DMF as a solvent, [6] SBA-15 functionalized D-2PA-Pd (II) catalyst for biphenyl synthesis using DMF as a solvent, [36] Suzuki-Miyaura cross-coupling using PdnpnSTDP in DMF:water solvent system. [37] These reactions employ potentially hazardous or environmentally unfriendly solvents, which must be replaced by more environmentally friendly solvents.…”
