P-Arylation in water has been developed via cross-coupling of arylhalides with diphenylphosphine oxide (Ph2P(O)H) and (RP)-(−)-menthyl benzylphosphinate catalyzed by NiCl2·6H2O/Zn under relatively mild conditions.
NiCl 2 ·6H 2 O / Zn催化的芳基卤化物与二苯基膦氧化物(Ph 2 P(O)H)和(R P)-(-)-薄荷基苄基次膦酸酯的交叉偶联已开发了水中的P-芳基化。相对温和的条件。
Palladium anchored on a covalent organic framework as a heterogeneous catalyst for phosphorylation of aryl bromides
A simple azine-linked covalent organic framework (COF) with high thermal and chemical stabilities has been prepared by using deep eutectic solvent (DES) as green media. The as-synthesized COF was employed as heterogeneous ligand for immobilization of PdII. The obtained Pd-supported COF nanoparticles catalyst (defined as Pd/TFPT-Azine-COF) was found to be an efficient heterogeneouscatalyst for the
mononuclear Tb(hfa)3 complexes with monodentate phosphine oxides and polynuclear Tb(hfa)3 complexes with bidentate phosphine oxides, the ΔEa and A values of polynuclear TbIII complexes were smaller than those of mononuclear TbIII complexes. Phosphorescence spectra and lifetimes of each Gd(hfa)3 complex revealed that excited states of hfa ligands in TbIIIcomplexes differed from those of the polynuclear
(L2) results in a two-dimensional (2D) network Sm(hfac)2(CF3COO)(L2)3}∞ (2) and near-white emission, but bis(diphenyl-phosphinoyl)-9,10-anthracene (L3) forms a zero-dimensional (0D) cyclic structure Sm(hfac)3(L3)}2 (3) with strong π⋯π interactions that emit green color. Noticeably, the conjugation change is accompanied by a configurational change of coordinationfrom trans for 1 and 2 to cis for 3.
