Publication date: Available online 21 April 2019Source: Journal of Organometallic ChemistryAuthor(s): Margaux Elie, Gilbert Umuhire Mahoro, Eric Duverger, Jean-Luc Renaud, Richard Daniellou, Sylvain GaillardAbstractCytotoxicity of cationic (NHC)Cu(I) complexes bearing 2,2′-dipyridylamine (dpa) type ligands has been evaluated toward 4 cancer cell lines, and compared to the one of neutral (NHC)Cu(I) complexes. The high cytotoxicity of these novel cationic (NHC)Cu(I) complexes, combined with the straightforward synthesis, and versatility of dpa type ligands may offer new prospects in cancer research, toward the developm...

Homoleptic cis- and trans-palladium(II) bis(guanidinato) complexes derived from N-aryl-N′,N″-di(pyridin-2-yl)- and N-aryl-N′,N″-bis(6-methylpyridin-2-yl)guanidines: Catalysts for Heck-Mizoroki coupling reactions
Publication date: Available online 20 April 2019Source: Journal of Organometallic ChemistryAuthor(s): Vishwesh Mishra, Jisha Mary Thomas, Sivasankar Chinnappan, Natesan ThirupathiAbstractN-Aryl-N′,N″-di(pyridin-2-yl)- and N-aryl-N′,N″-bis(6-methylpyridin-2-yl)guanidines (1–4 and 5–7) were isolated in 75%–81% yields. Reactions of Pd(OAc)2 with guanidines 2–7 carried out separately in toluene at 60 °C for 3 h afforded 8–13 respectively in 69%–80% yields. Compounds 1–13 were characterized by elemental analyses, HR-MS, IR and NMR (1H and 13C) spectroscop...

Amphiphilic bimetallic polymer as single-source precursors for the one-pot synthesis of L10-phase FePt nanoparticles
Publication date: Available online 20 April 2019Source: Journal of Organometallic ChemistryAuthor(s): Zhengong Meng, Zhuoxun Wei, Kuo Fu, Lei Lv, Zhen-Qiang Yu, Wai-Yeung WongAbstractAmphiphilic polymers have attracted extensive research attention in constructing various nanostructures by self-assembly. Here we designed and synthesized two amphiphilic bimetallic polymers with different length of the tails P1 and P2, in which Fe,Pt-containing conjugated complex acted as the hydrophobic block and hydrophilic poly(ethylene glycol) (PEG) was bonded to the bimetallic core as the flexible tails. P1 and P2 were used as the single...

Crosslinked polymers based on polyborosiloxanes: Synthesis and properties
Publication date: Available online 20 April 2019Source: Journal of Organometallic ChemistryAuthor(s): Fedor V. Drozdov, Sergey A. Milenin, Vadim V. Gorodov, Nina V. Demchenko, Michail I. Buzin, Aziz M. MuzafarovAbstractIn current work, crosslinked polyborosiloxanes (PBS) were synthesized by the Piers-Rubinsztajn reaction based on polydimethylsiloxanes (PDMS) with terminal dimethylhydrosilyl or distributed methylhydrosilyl groups in the polymer chain and boronic or phenyl boronic acid methyl esters. Depending on the number and location of the methylhydrosilyl groups in the initial PDMS, as well as on the functionality of th...

Synthesis and structural characterisation of 1’-(diphenylphosphino)ferrocene-1-phosphonic acid, its ammonium salts and Pd(II) complexes
Publication date: Available online 17 April 2019Source: Journal of Organometallic ChemistryAuthor(s): Filip Horký, Ivana Císařová, Jiří Schulz, Petr ŠtěpničkaAbstractA new polar phosphinoferrocene ligand, viz. 1’-(diphenylphosphino)ferrocene-1-phosphonic acid (H2L), was prepared by hydrolysis of the corresponding phosphonate ethyl ester. However, the compound is relatively unstable, gradually decomposing upon prolonged storage, ultimately affording phosphine oxide H2LO. When the phosphine moiety was protected (e.g., in phosphine oxide H2LO and adduct H2L·BH3), no decompos...
