Guedes da Silva, Antonin LyčkaAbstractA series of four new long chain triorganotin(IV) esters containing a diazenyl- and an imino-groups appended with ferrocene scaffold were designed and synthesized. Ferrocene based metallo pro-ligands H'HFcL1 and H'HFcL2 were obtained by reacting isomeric 3-/4-ferrocenylanilines with 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1-diazenyl]benzoic acid, which upon reactions with appropriate triorganotin(IV) precursors...

Highly active tridentate amino-phenol zinc complexes for the catalytic ring-opening polymerization of ε-caprolactone
Publication date: Available online 15 December 2018Source: Journal of Organometallic ChemistryAuthor(s): Qian Hu, Suyun Jie, Pierre Braunstein, Bo-Geng LiAbstractTridentate 2,6-bis(imino)phenol (L1−L4) and 2,6-bis(amino)phenol (L5−L7) ligands and their corresponding zinc chloride complexes (1–7) have been synthesized and well characterized by FT-IR, 1H and 13C NMR, elemental analysis and single-crystal X-ray diffraction analysis. It was found that zinc complexes (1–4) with 2,6-bis(imino)phenol ligands were inactive for the ring-opening polymerization (ROP) of ε-caprolactone (ε-CL) ev...

Synthesis and characterization of tetracarbonylmolybdenum(0) and pentacarbonyltungsten(0) complexes of TADDOL-derived, monodentate P-donor ligands
Publication date: 15 February 2019Source: Journal of Organometallic Chemistry, Volume 881Author(s): Ethan C. Cagle, Gary M. GrayAbstractTADDOL-derived P-donor ligands are of interest as ligands in transition metal catalyzed transformations; however, few studies have been conducted on the steric and electronic properties of P-donor ligands derived from TADDOL. To gain more insight into these properties four tetracarbonylmolybdenum(0) and two pentacarbonyltungsten(0) complexes of monodentate P-donor ligands derived from TADDOL have been studied. These studies show that exchanging the chloro substituent on the phosphorus for ...

An efficient and simple imidazole-hydrazone ligand for palladium-catalyzed Suzuki-Miyaura cross-coupling reactions in water under infrared irradiation
Publication date: 1 February 2019Source: Journal of Organometallic Chemistry, Volume 880Author(s): Martín Camacho-Espinoza, José Guillermo Penieres-Carrillo, Hulme Rios-Guerra, Selene Lagunas-Rivera, Fernando Ortega-JiménezAbstractA highly efficient catalytic system based on Pd(OAc)2 and an imidazole-hydrazone ligand has been developed for Suzuki–Miyaura cross-coupling reaction in water under aerobic conditions using IR-irradiation. The system can tolerate a wide range of functionalized arylboronic acids and aryl halides. Furthermore, this protocol is also applicable for hetero-aryl bromides.Grap...

The phosphinoboration of 2-diphenylphosphino benzaldehyde and related aldimines
Publication date: 1 February 2019Source: Journal of Organometallic Chemistry, Volume 880Author(s): Meagan B. Kindervater, Justin F. Binder, Samuel R. Baird, Christopher M. Vogels, Stephen J. Geier, Charles L.B. Macdonald, Stephen A. WestcottAbstractWe have investigated the addition of a simple phosphinoboronate ester, Ph2PBpin (pin = 1,2-O2C2Me4), to 2-diphenylphosphinobenzaldehyde (2-Ph2PC6H4C(O)H) and related aldimine derivatives (2-Ph2PC6H4C(NR)H) as a simple and effective strategy for generating unique diphosphine ligands bearing a pendant Lewis-acid Bpin group. These reactions proceed selectively to give one new p...

Syntheses, structures and in vitro cytostatic activity of four novel homochiral organotin(IV) phosphonates
Publication date: 15 February 2019Source: Journal of Organometallic Chemistry, Volume 881Author(s): Bo-Hang An, Ru-Fen Zhang, Qian-Li Li, Xiu-Mei Du, Jing Ru, Shao-Liang Zhang, Chun-Lin MaAbstractFour novel homochiral organotin phosphonates, namely, (R)-, (S)-[(Me3Sn)2(pemp)(H2O)]n (1, 2) and (R) -, (S)-[(Ph3Sn)2(pemp)2]n (3, 4) [pempH2 = (R)- or (S)-(1-phenylethylamino) methylphosphonic acid], were synthesized and characterized by X-ray diffraction analysis, elemental analysis, FT-IR, NMR (1H, 13C, 31P and 119Sn), TGA (thermogravimetric analysis) and CD (circular dichroism spectra). The structure analysis indicates t...

Iron-catalyzed regioselective cyclotrimerization of alkynes to benzenes
We report the synthesis and characterization of simple di(aminomethyl)pyridine ligated iron-pincer complexes, which catalyzed the regioselective [2 + 2+2] cyclotrimerization of terminal aryl and alkyl alkynes to provide the 1,2,4-trisubstituted benzene molecules. Interestingly, internal alkynes also exhibited similar cyclization and resulted in hexa-substituted benzene compounds. Increased steric bulk on pincer ligands diminished the selectivity for cycloaddition. Cyclotrimerization reactions proceeded at room temperature upon activation of catalyst by a Grignard reagent. EPR studies indicated thermally induced s...
