“…Nitrogen ligands, such as amine [33e36], diazabutadienes [37], oxazolines [38e40], and hydrazones [41] have attracted considerable interest due to their stability and excellent activity. Examples of Schiff base derived systems, such as cyclopalladated imine [42,43], multi-or bi-dentate imine ligands [44e49] have been extensively investigated and successfully employed in catalytic transformations, while research on monodentate imine ligand remains scarce to date [50]. Here we report a highly efficient catalyst system for Suzuki cross-coupling using simple monodentate imine palladium complexes.…”

An unprecedented reactivity profile of biochemically relevant R-benzofuroxan (R=H, Me, Cl), with high structural diversity and molecular complexity on a selective {Ru(acac) } (acac=acetylacetonate) platform, in conjugation with EtOH solvent mediation, is revealed. This led to the development of monomeric [Ru (acac) (L )] (1 a-1 c; L =2-nitrosoanilido derivatives) and dimeric [{Ru (acac) } (L )] (2 a-2 b; L =(1E,2E)-N ,N -bis(2-nitrosophenyl)ethane-1,2-diimine derivatives) complexes in one pot with a change in the metal redox conditions. The functionalization of benzofuroxan in 1 and 2 implied in situ reduction of N=O to NH in the former and solvent-assisted multiple N-C coupling in the latter. The aforesaid transformation processes were authenticated through structural elucidation of representative complexes, and evaluated by their spectroscopic/electrochemical features, along with C D OD labeling and monitoring of the impact of substituents (R) in the benzofuroxan framework on the product distribution process. The noninnocent potential of newly developed L and L in 1 and 2, respectively, was also probed by spectroelectrochemistry in combination with DFT calculations.

Schiff Bases as Inspirational Motif for the Production of Ni(II) and Pd(II) Coordination and Novel Non‐Symmetric Ni(II)‐POCOP Pincer Complexes

The synthesis of Ni(II) and Pd (II) coordination complexes containing Schiff's bases derived from the condensation of 2,4dihydroxybenzaldehyde with 4-chloroaniline (L1) or 3,5-dichloroaniline (L2) is described. The condensation of ligands L1 and L2 with chlorodiisopropylphosphine in the presence of a base produced the corresponding non-symmetric pincer ligands POCOP-1 and POCOP-2 with the unexpected CÀ P bond formation by a hydrophosphorylation of the imine process. The new CÀ P bond formation probably occurring by a Kabachnik-Field mechanism type without the requirement of catalysts or additional reagents. Further treatment of ligands POCOP-1 or POCOP-2 with NiCl 2 afforded the non-symmetric pincer complexes Ni(II)-POCOP-1 and Ni(II)-POCOP-2. The crystal structures of L1, 3, Ni(II)-POCOP-1 and Ni(II)-POCOP-2 were unequivocally determined by single crystal X-ray diffraction studies. In addition, the metal complexes were used as catalysts in Suzuki-Miyaura couplings under microwave irradiation, being the Pd(II) derivatives the best catalysts of the series when compared to their Ni(II) analogues under the same reaction conditions.
