Novel hetero-binuclear platinum complexes (HBC-Pt(II)-M(II), M = Ca(II), Mg(II), Zn(II), and Cd(II)) have been synthesized by the reaction of the corresponding precursors [Pt(ppy)(μ-Cl)]2 with (2-(1H-tetrazol-5-yl)phenyl)diphenylphosphine oxide (TTPPO). The x-ray structures of the complexes show that two ancillary ligands TTPPO in the square-planar Pt(II) moiety act as a quadridentate chelating agent for the other metal center, eventually forming a distorted octahedral configuration. There are no significant π-π interactions and Pt-M metallophilic interactions in the crystal lattice, due to the steric hindrances associated with the rigid octahedral structure together with the bulky TTPPO. Consequently, HBC-Pt-M complexes show monomer emission characteristics with quantum yields up to 59% in powder, suggesting their great potential for practical applications. DFT and TD-DFT calculations on HBC-Pt-Zn reveal that the phosphorescence can be ascribed to intraligand charge transfer (3ILCT) combined with some metal-to-ligand charge transfer (3MLCT) in the Pt(ppy) moiety, which is consistent with the observations from the photophys. investigations. The experimental process involved the reaction of 2-Bromobenzonitrile(cas: 2042-37-7Category: nitriles-buliding-blocks)

Liu, Yanhong; Han, Zhe; Yang, Yiying; Zhu, Rongxiu; Liu, Chengbu; Zhang, Dongju published their research in Molecular Catalysis in 2021. The article was titled 《DFT study on synergetic Ir/Cu-metallaphotoredox catalyzed trifluoromethylation of aryl bromides》.Product Details of 623-00-7 The article contains the following contents:

MacMillan et al. recently developed an elegant strategy for trifluoromethylation of aryl halides by merging iridium photoredox catalysis with copper catalysis [Science 360 (2018) 1010-1014]. The present work presents a complementary theor. study to better understand the dual photoredox-copper catalysis. Calculated results confirm that the most possible photoredox catalytic cycle proceeds via a reductive quenching mechanism (IrIII/*IrIII/IrII/IrIII) with supersilanol as quencher and the CF3 reagent as oxidant. The formation of aryl radical involves three essential steps: deprotonation of the oxidized supersilanol by Na2CO3 to form the O-centered radical species, SiMe3 group migration to give the Si-centered silyl radical, bromine atom abstraction from aryl bromide. The CF3 radical can be obtained via the fragmentation process of the reduced CF3 reagent. The additions of both aryl radical and CF3 radical on the CuI center generates CuIII complex, from which the desired trifluoromethylation product is obtained via the C(sp2)-CF3 reductive elimination. All these processes were found to involve low barriers, and the highest one is only 12.7 kcal/mol, providing support of the viable trifluoromethylation strategy using copper catalysis via the radical trapping mechanism rather than the conventional oxidative addition mechanism. The results came from multiple reactions, including the reaction of 4-Bromobenzonitrile(cas: 623-00-7Product Details of 623-00-7)

Wang, Chang-Sheng; Yu, Yongqi; Sunada, Yusuke; Wang, Chen; Yoshikai, Naohiko published an article in 2022. The article was titled 《Cobalt-Catalyzed Carbo- and Hydrocyanation of Alkynes via C-CN Bond Activation》, and you may find the article in ACS Catalysis.Related Products of 1194-02-1 The information in the text is summarized as follows:

Cobalt-catalyzed carbo- and hydrocyanation reactions of alkynes via C-CN bond cleavage of organic cyanides are reported. A low-valent cobalt-diphosphine catalyst generated by reduction with Zn promotes the arylcyanation of alkynes with trans-selectivity. By contrast, the addition of Zn(OTf)2 to this catalytic system not only accelerates the transformation but also switches the stereoselectivity, affording cis-arylcyanation products. The present catalytic systems prove to be effective for alkenylcyanation using alkenyl cyanides as well as for transfer hydrocyanation using propionitrile as the HCN surrogate. Exptl. and computational studies on arylcyanation have been performed to gain insight into the reaction pathways, including the possible origin of the stereodivergence under cobalt and cobalt/zinc catalysis.
