“…Various reactions for forming a C–C bond are currently under study because of their significant applications . Among them, the Mizoroki–Heck reaction is, perhaps, the most strategic process for the arylation of olefins through palladium‐catalyzed C–C formation reactions . Although numerous attempts at designing a green, simple, cost‐effective, and efficient approach for this reaction have been made, there is still ample scope for improvement.…”

The complexes PdII(qcq)(OAc) and PtII(qcq)Cl have been synthesized using environmentally benign synthesized ligands and characterized by elemental analyses: Fourier transform infrared spectroscopy, UV–visible spectroscopy, 1H NMR spectroscopy, and X‐ray diffraction. The catalytic activity of the complex was assessed, in different media, for the Mizoroki–Heck coupling reaction for typical aryl halides and terminal olefins under aerobic conditions. Since the base and the solvent were found to influence the efficiency of the reaction, reaction conditions, temperature, time, and the amount of K3PO4 and a mixture of H2O/PEG, were optimized. We found, for the Mizoroki–Heck reaction coupling less reactive aryl chloride derivatives with olefins, promising activity for palladium catalysts. The electrochemical behavior of Hqcq and the Pd(II) complex was investigated by cyclic voltammetry and irreversible PdII/I reductions were observed. Hqcq and the Pd(II) and Pt(II) complexes were also screened for their in vitro antibacterial activity. They showed promising antibacterial activity comparable to that of the antibiotic penicillin.

“…After six successive cycles, the Cu-AIA-PC-Pd catalystr emains substantially active and no significant decreasesi nt he catalytic efficiency are observed ( Figure S22). Compared with the catalysts reported in literatures (TableS5), [73][74][75][76][77][78][79][80][81][82][83] the obtained Cu-AIA-PC-Pd also exhibits excellentc atalytic activity.T he results confirm that Cu-AIA as a2 Dcarriertos upport metal catalysts is feasible.…”

With the assistance of hydrogen bonds of the o‐amino group, we have successfully tuned a coordination structure from a metal–organic polyhedron (MOP) to a two‐dimensional (2D) metal–organic framework (MOF). The amino group forms hydrogen bonds with the two vicinal carboxylic groups, and induces the ligand to coordinate with copper ions to form the 2D structure. The obtained 2D Cu‐based MOF (Cu‐AIA) has been applied as an efficient heterogeneous catalyst in the aerobic epoxidation of olefins by using air as oxygen source. Without the aggregation problem of active sites in MOPs, Cu‐AIA possesses much higher reactivity than MOP‐1. Furthermore, the amino group of the framework has been used as a modifiable site through post‐synthetic metalation (PSMet) to prepare a 2D MOF‐supported Pd single‐site heterogeneous catalyst, which shows excellent catalytic performance for the Suzuki reaction. It indicates that Cu‐AIA can also work as a good 2D MOF carrier for the derivation of other heterogeneous catalysts.

“…During the past three decades, pincer palladium catalysts have been developed and used for cross‐coupling reactions. [ 22,45 ] Hence, the catalytic activities of complexes 2a–c were evaluated in Suzuki–Miyaura couplings (Scheme 8). [ 34,40 ] For this purpose, the reactions were performed using phenyl bromide, phenylboronic acid, 0.1 mol‐% of catalyst, K 2 CO 3 , toluene at 100 °C for 90 min.…”

The use of XCX‐aryl pincer metal complexes as catalysts started immediately after their discovery in 1976. Nowadays pincer metal complexes are commonly used as a new platform for the development and improvement of known and novel catalytic reactions. More recently, pincer metal complexes with hybrid pincer backbones of the type POCZP (Z = CH2, NH or S) have attracted much attention because of their facile preparation and outstanding catalytic performances. For instance, these complexes have been successfully used in cross‐coupling, transfer hydrogenation, and borylation reactions. In many cases, showing enhanced catalytic activities compared with POCOP‐ or PZCZP‐aryl pincer metal analogues. Hence, in this Minireview we summarize the available synthetic routes to produce POCZP aryl pincer ligands and their metal complexes as well as their applications as catalysts in different organic transformations.
